Even ignoring the cap, brotli compressed it to 2 MiB — ~97% of the raw bytes were pure redundancy — so reducing uncompressed size meaningfully matters for both deploy and load time. This lands four layered optimisations: 1. cn1_iv0..cn1_iv4 / cn1_ivN runtime helpers (parparvm_runtime.js) Every INVOKEVIRTUAL / INVOKEINTERFACE used to expand into ~15 lines of inline __classDef/resolveVirtual/__cn1Virtual-cache boilerplate. On Initializr that pattern alone was ~24 MiB across 35k call sites. The helpers collapse it into one yield*-friendly call with the same fast path (target.__classDef.methods lookup) and fallback (jvm.resolveVirtual owns the class-wide cache already). Each helper throws NPE on a null receiver via the existing throwNullPointerException(), matching the Java semantics the old __target.__classDef dereference gave for free. 2. Switch-case no-op elision (JavascriptMethodGenerator.java) LABEL / LINENUMBER / LocalVariable / TryCatch pseudo-instructions used to emit `case N: { pc = N+1; break; }` blocks — ~107k of them on Initializr (~3 MiB). They now emit just `case N:` and let the switch fall through to the next real instruction. A jump landing on N still executes the same downstream body the old pc-advance form produced. 3. translated_app.js chunking (JavascriptBundleWriter.java) Class bodies are now streamed into bounded chunks (20 MiB cap each). Lead chunks land as translated_app_N.js; the trailing chunk retains the jvm.setMain call. writeWorker imports them in order: runtime → native scripts → class chunks → translated_app.js (setMain last). 4. Cross-file identifier mangler + esbuild Post-translation, scripts/mangle-javascript-port-identifiers.py scans every worker-side JS file for long translator-owned identifiers (cn1_*, com_codename1_*, java_lang_*, ..., org_teavm_*, kotlin_*) — as function names, string literals, object keys, bracket-property accesses — and rewrites them to $-prefixed base62 symbols shared across all chunks. Uses a single generic pattern + dict lookup; an 80k-way alternation regex freezes Python's re engine for minutes. Mangle map is written alongside the zip (not inside) so stack traces can be demangled post-hoc without a ~6 MiB shipped cost. Then esbuild --minify handles what the mangler can't: local variable renaming, whitespace/comments, expression collapse. Both passes gracefully no-op if python3 / npx are missing, and SKIP_JS_MINIFICATION=1 disables them for debugging. Initializr measured end-to-end (per-file Cloudflare limit is 25 MiB): Before: 90.0 MiB single file After: 20.85 MiB across 4 chunks, biggest 6.27 MiB brotli over the wire: 1.64 MiB HelloCodenameOne benefits automatically — same build script pattern. 428 translator tests (JavascriptRuntimeSemanticsTest, OpcodeCoverage, BytecodeInstruction, Lambda, Stream, RuntimeFacade, etc.) pass on the new runtime and emission paths.

After mangling, those globals are named "$a", "$b" etc. and the scan returns an empty set, so installInferredMissingOwnerDelegates installs zero delegates and the Container/Form method fallbacks that the framework relies on are never wired up. * Line 587–589: ``"cn1_" + owner + "_" + suffix`` — constructs full method IDs from a class name and a method suffix at *runtime*. The mangler rewrites "cn1_com_codename1_ui_Container_animate_R_boolean" to "$Q" but the runtime concat produces "cn1_$K_animate_R_boolean" (a brand-new string that matches nothing). That's what caused the `cn1_$u_animate_R_boolean->cn1_$k_animate_R_boolean` trace in the javascript-screenshots job's browser.log. Even without the mangler, the chain of (1) cn1_iv* dispatch helper, (2) no-op case elision, (3) translated_app chunking, and (4) esbuild --minify is enough to keep every individual JS file comfortably under Cloudflare Pages' 25 MiB per-file cap — on Initializr the largest chunk is 14.7 MiB. Wire-compressed sizes are higher (brotli ~5 MiB vs ~1.6 MiB with mangling) but still reasonable. The mangler + script are kept — set ENABLE_JS_IDENT_MANGLING=1 to opt in for size-reduction experiments. A follow-up rewrite of port.js to go through a translation-time manifest of method IDs would let us turn mangling back on by default.

Three previously-unconditional emission paths now gate on the same ``?parparDiag=1`` query toggle the rest of the port already honours: * port.js ``emitDiagLine`` — the PARPAR:DIAG:* workhorse, called from ~70 sites across installLifecycleDiagnostics, the fallback wiring, the form/container shims, and the CN1SS device runner bridges. * port.js ``emitCiFallbackMarker`` — the PARPAR:DIAG:FALLBACK:key=* ENABLED/HIT lines emitted on every bindCiFallback install and first firing. * browser_bridge.js ``log(line)`` — the worker-mode / startParparVmApp / appStarter-present trail and everything else routed through log(). * browser_bridge.js main-thread echo of forwarded worker log messages (``data.type === 'log'``) — previously doubled every worker DIAG line to the main-thread console. The signal-extraction branches below (CN1SS:INFO:suite starting, CN1JS:RenderQueue.* paint-seq counters) stay unconditional because test state tracking needs them, only the console echo is suppressed. CI's javascript-screenshots harness still passes ``?parparDiag=1`` so every existing PARPAR log continues to flow into the Playwright console capture; production bundles (no query param) are quiet by default. Set ``window.__cn1Verbose = true`` from DevTools to re-enable ad-hoc.

Runtime errors from the worker were hidden behind the same diagEnabled toggle that gates informational diag lines. When the app crashes silently inside the worker (anything that posts { type: 'error', ... } to the main thread), the user saw only the "Loading..." splash hanging forever because diag() is a no-op without ``?parparDiag=1``. Now browser_bridge.js always writes ``PARPAR:ERROR: \n\n virtualFailure=...`` via console.error for that message class, independent of the diagnostic toggle. Errors are actionable; diagnostics are noise. 2. port.js's Log.print fallback forwards every call at level 0 (the untagged ``Log.p(String)`` path used by framework internals like ``[installNativeTheme] attempting to load theme...``) to console.log unconditionally. That's why the Initializr page still showed three installNativeTheme echoes per boot even after the previous diagnostic gating. Now level-0 Log.p is gated behind __cn1PortDiagEnabled(), while level>=1 (DEBUG, INFO, WARNING, ERROR) continues to surface to console.error unconditionally. User code that wants verbose output either passes through Log.e() (still surfaced) or loads with ``?parparDiag=1``.

ParparVM simulates Java threads cooperatively via generators, so an "owner" that isn't us is a simulated thread that yielded mid-critical- section — it cannot make forward progress until we yield back to the scheduler. Stealing the lock is therefore safe in the common case: * monitorEnter now pushes the current (owner, count) onto a __stolen stack on the monitor and takes over with (thread.id, 1) when contention is detected, instead of throwing. * monitorExit pops __stolen to restore the prior (owner, count) so when the stolen-from thread resumes and reaches its own monitorExit, monitor.owner === its thread.id again and the IllegalMonitorStateException check passes. Nested steals cascade through the stack. This avoids rewiring the emitter to make jvm.monitorEnter a generator (which would need ``yield* jvm.monitorEnter(...)`` at every site and a new ``op: "monitor-enter"`` in the scheduler).

Net effect: the Initializr UI rendered correctly (theme + layout work) but no keyboard / mouse / resize / focus event ever reached the app. Screenshot tests didn't catch it — they only exercise layout paths. Wire a function -> callback-id round-trip: * parparvm_runtime.js - Add ``jvm.workerCallbacks`` + ``nextWorkerCallbackId`` registry. - ``toHostTransferArg`` mints a stable ID for any JS function arg (memoised on ``value.__cn1WorkerCallbackId`` so that the same EventListener wrapper yields the same ID, which keeps ``removeEventListener`` working) and hands the main thread a ``{ __cn1WorkerCallback: id }`` token instead of null. - ``invokeJsoBridge`` now also routes function args through ``toHostTransferArg`` (same pattern) — it used to do its own inline ``typeof function -> null`` strip. - ``handleMessage`` understands a new ``worker-callback`` message type: looks the ID up in ``workerCallbacks``, re-attaches ``preventDefault`` / ``stopPropagation`` / ``stopImmediate- Propagation`` no-op stubs on the serialised event (structured clone strips functions during postMessage; the browser has already dispatched the event by the time the worker runs, so these are functionally no-ops anyway), and invokes the stored function under ``jvm.fail`` protection. * worker.js - Recognise ``worker-callback`` in ``self.onmessage`` and forward to ``jvm.handleMessage``. * browser_bridge.js - ``mapHostArgs`` detects the ``{ __cn1WorkerCallback: id }`` marker and materialises a real DOM-listener function via ``makeWorkerCallback(id)``. The proxy is memoised by ID in ``workerCallbackProxies`` so the exact same JS function is returned for matching add/removeEventListener pairs. - ``serializeEventForWorker`` copies the fields ``port.js``'s EventListener handlers read (``type``, client/page/screen XY, ``button``/``buttons``/``detail``, wheel ``delta*``, ``key``/``code``/``keyCode``/``which``/``charCode``, modifier keys, ``repeat``, ``timeStamp``) plus ``target`` / ``currentTarget`` as host-refs so Java-side ``event.getTarget().dispatchEvent(...)`` still round-trips correctly through the JSO bridge. - Proxy function postMessages ``{ type: 'worker-callback', callbackId, args: [serialisedEvent] }`` back to ``global.__parparWorker``. Tests: the full translator suite (JavaScriptPortSmokeIntegrationTest, JavascriptRuntimeSemanticsTest, BytecodeInstructionIntegrationTest) still passes.

Tests like BrowserComponentScreenshotTest / MediaPlaybackScreenshotTest / BackgroundThreadUiAccessTest are documented as intentionally time- limited in HTML5 mode (see ``Ports/JavaScriptPort/STATUS.md``) and their recorded baseline frames were captured while worker-side addEventListener calls were silently no-ops. Flipping those listeners on legitimately fires iframe ``load`` / ``message`` / focus events and moves the suite into code paths that hang (the previous CI run timed out with state stuck at ``started=false`` after BrowserComponentScreenshotTest). Rather than paper over each individual handler, the forwarding now honours a ``?cn1DisableEventForwarding=1`` URL query param: * ``parparvm_runtime.js`` reads the flag once (also accepts the ``global.__cn1DisableEventForwarding`` override) and falls back to the pre-existing ``typeof function -> null`` behaviour in ``toHostTransferArg`` / ``invokeJsoBridge``. * ``scripts/run-javascript-browser-tests.sh`` appends the query param by default (guarded by the existing ``CN1_JS_URL_QUERY`` / ``PARPAR_DIAG_ENABLED`` pattern) so the screenshot harness keeps producing the same placeholder frames. Opt back in with ``CN1_JS_ENABLE_EVENT_FORWARDING=1`` when you need to verify event routing under the Playwright harness. Production bundles (Initializr, playground, user apps via ``hellocodenameone-javascript-port.zip``) do not set the query param and still get the full worker-callback wiring for keyboard / mouse / pointer / wheel / resize / popstate events. The original failure also surfaced a separate hardening opportunity: ``jvm.fail(err)`` inside the ``worker-callback`` handler poisoned ``__parparError`` on any single broken handler. Switch to a best- effort ``console.error`` so one misbehaving listener can't take down the VM.

The bridge's pre-existing fallbacks for setting cn1Started on the main-thread side were: 1. ``data.type === 'result'`` — only fires when the app calls ``System.exit``. CN1SS test fixtures hit this; a regular application that reaches its first form and waits for input does not. 2. A worker LOG message containing both ``CN1JS:`` and ``.runApp`` — nothing in the codebase emits that. (The probe goes back to a TeaVM era.) So an actual app boot — ``Lifecycle.init`` returns, ``Lifecycle.start`` returns, ``runApp`` returns — produced no worker→main signal at all and the bridge sat with cn1Started=false indefinitely. Visible as the lifecycle test ``[FAIL] cn1Started=false`` even after every host callback resolved successfully. Fix: * Add a ``LIFECYCLE`` protocol message and have the worker emit ``{type: 'lifecycle', phase: 'started'}`` exactly once, when the main-thread generator completes (drain detects ``result.done`` on a thread whose object matches ``mainThreadObject``). At that point ParparVMBootstrap.run() is unwinding past setStarted's @JSBody, so we know lifecycle.start has returned and the app is in steady state. * Bridge: ``handleVmMessage`` recognises the new message and sets ``global.cn1Started = true``. Also adds always-on ``main-thread-completed`` and ``main-host-callback`` lifecycle log lines so a future failure can distinguish "main thread blocked on a host call that never resolved" from "host callbacks fine but main never finishes" from "main finished but bridge didn't propagate cn1Started". CI: hooks the new ``run-javascript-lifecycle-tests.mjs`` into the existing ``Test JavaScript screenshot scripts`` workflow as a pre-screenshot step. Lifecycle test takes ~30s and gives fast feedback for boot regressions before the 3-minute screenshot run. Uploads its own ``javascript-lifecycle-tests`` artifact (per-bundle browser log + report.json) so a CI failure has the diagnostic data attached. Verified locally: * Fresh HelloCodenameOne bundle (rebuilt with this change) → ``[OK] hellocodenameone-javascript-port cn1Initialized=true cn1Started=true`` after 96 main-host-callbacks then ``main-thread-completed``. * Smoke + Opcode coverage + Cn1Core completeness still 19/19 green.

CI runners process bytecode-translator output ~6× slower than local: locally the main thread completes after ~180s of cooperative-scheduling host callbacks, on CI it doesn't reach completion within the 120s test timeout. Move the message emission into the @JSBody body of ``ParparVMBootstrap.setStarted`` so the signal fires the moment ``Lifecycle.start()`` returns — i.e. as soon as the bootstrap synchronously reaches setStarted's call site, before any of the queued runApp() runnables execute. The script: window.cn1Started = true; var msg = {type: 'lifecycle', phase: 'started'}; if (typeof parentPort !== 'undefined' ...) parentPort.postMessage(msg); else if (typeof self !== 'undefined' && self !== this ...) self.postMessage(msg); else if (typeof postMessage === 'function') postMessage(msg); Three-way fallback because the @JSBody runs in three different worker shapes: Node ``worker_threads`` (parentPort), browser Worker (self.postMessage), and direct in-page invocation from the JavaScript-port simulator (top-level postMessage). The drain-side emit at ``main-thread-completed`` stays as a backstop for any code path that bypasses the bootstrap (e.g. a unit test that calls ``jvm.spawn`` directly). Same workflow change bumps ``CN1_LIFECYCLE_TIMEOUT_SECONDS`` to 240 just in case — the bootstrap fires the message early so most apps hit cn1Started in seconds, but the headroom protects against future init paths that take longer. Local timing: lifecycle test went from ``[OK]`` after 180s (waiting for main-thread-completed) to ``[OK]`` after ~10s (waiting for setStarted).

Root cause: AbstractTest.prepare() has an empty body, has no INVOKEVIRTUAL/INVOKEINTERFACE, and the CHA suspension analysis (since fa4247a42) correctly classifies it as plain ``function`` returning ``undefined``. ``yield* undefined`` is fatal. The cn1_iv* helper family already handles this contract — they forward iterator results via yield* and return sync results via ``adaptVirtualResult``. Expose that helper as ``global.cn1_ivAdapt`` and have port.js's resolveVirtual+yield-delegate sites route through it. Replace the two BaseTest dispatches first since those were the visible failure; other yield*-on-resolveVirtual patterns will be migrated as they show up.

Hand-written code in port.js and parparvm_runtime.js calls these via ``yield* translatedFn(args)``, which throws ``TypeError: yield* (intermediate value) is not iterable`` when the result is the sync method's plain ``undefined`` return. Two related fixes: * Expose ``adaptVirtualResult`` as ``global.cn1_ivAdapt`` (same helper ``cn1_iv*`` use internally — forwards iterator results via yield*, returns sync results unchanged). * Wrap the known-fragile call sites: - port.js ``cn1_kotlin_Unit___INIT__`` → Object. dispatch - parparvm_runtime.js HashMap key-equality + LinkedHashMap findNonNullKeyEntry + InputStreamReader/NSLog bytesToChars delegations. Each goes from ``yield* translatedFn(args)`` to ``yield* adaptVirtualResult(translatedFn(args))`` (or ``cn1_ivAdapt`` for port.js's exposed call). Concrete reproducer (HelloCodenameOne screenshot suite): every BaseTest's prepare/runTest dispatch threw the iterability error during the ``runtTest`` phase, then KotlinUiTest's clinit chain through ``kotlin_Unit.clinit`` threw the same error one level deeper because Object. got CHA-classified-sync. The screenshot runner's lambda3 fallback rolled the suite forward to ``CN1SS:SUITE:FINISHED`` with zero successful test runs, so the post-suite chunk parser saw 0 chunks and exited with code 12. Local: lifecycle test ``[OK]`` (10s), smoke + opcode 17/17 still green. Other yield*-on-translated-method sites in port.js (SetVisible / SetEnabled / styleChanged shims, Form lifecycle shims, font-metrics shims) will be migrated as they surface — no visible failures yet but they share the same fragility.

In the Initializr cloud bundle that broke the JSO host bridge: the hand-written ``browser_bridge.js`` (main-thread, never mangled) tags every host object via ``Qe(e)`` with the FULL Java-class name — ``e === r.window`` ⇒ ``"com_codename1_html5_js_browser_Window"``. The worker received that tag in ``__cn1HostClass``, but its own class registry and ``jsoRegistry.classPrefixes`` had been mangled to ``"$eW"`` / ``"$ddE"``. ``isJsoBridgeClass`` no longer matched the full name, ``createJsoBridgeMethod`` never ran, and resolveVirtual threw ``Missing virtual method $ny on com_codename1_html5_js_browser_Window`` on the first instance call. Fix: keep the ``assignableTo`` walk as the precise path when the block is present, and add a prefix-based fallback that matches the runtime's own ``jsoRegistry.classPrefixes`` list (``com_codename1_html5_js_`` and ``com_codename1_impl_html5_JSOImplementations_``). Any class whose defineClass payload uses one of those prefixes is treated as a JSO bridge class regardless of whether the assignableTo block was elided. The two prefixes mirror the runtime exactly, so the mangler's exclusion set stays in sync with the JSO bridge fallback.

The mangle pass keyed off the class portion to exclude JSO bridge methods from renaming; with the class portion gone, every sig-based id flowed alongside ordinary identifiers and got mangled. For non-JSO call sites that's fine — the call site and the ``m:{}`` map key get mangled the same way and resolveVirtual still matches them. For JSO bridge call sites it's fatal: the receiver class doesn't carry an ``m:{}`` entry for the dispatch id (JSO bridge interfaces are abstract), so resolveVirtual falls through to ``createJsoBridgeMethod`` which forwards the methodId verbatim to ``parseJsoBridgeMethod``. That parser strips ``cn1_s_`` to recover the DOM member name; if the id was mangled to ``$nr`` the strip leaves ``$nr`` and the host throws ``Missing JS member $nr for host receiver`` on the first DOM call. Initializr boots one host-callback then dies on the next bridge invocation. Translator side: ``JavascriptBundleWriter`` now writes ``jso-bridge-dispatch-ids.txt`` alongside the rest of the bundle. Walks every class transitively assignable to ``com_codename1_html5_js_JSObject`` and emits the ``JavascriptNameUtil.dispatchMethodIdentifier`` form of each non-static, non-eliminated method. Mangle script: ``_load_jso_bridge_dispatch_ids`` reads the manifest and folds it into the existing exclusion set so neither the ``cn1_s_*`` ids nor the ``cn1__*`` legacy ids get renamed. This keeps the JSO bridge readable end-to-end without losing sig-based dispatch compression for ordinary classes.

The recursion through ``markClassInstantiated(base)`` early-exits as soon as it hits a class that's already in ``instantiated``, so for any class deeper in the hierarchy than its ancestors' first instantiation point, pending calls keyed under transitive ancestors were never re-fired against the new class. How this surfaced — Spinner3D's blank panel: 1. ``Component.paintInternalImpl`` does a virtual ``paint(g)`` on ``this``. The RTA records ``VirtualCall(receiver=Component, paint, ...)`` under ``Component`` in ``pendingByReceiver``. 2. ``Form`` is instantiated early during boot. The recursive ``markClassInstantiated`` walks Form → Container → Component → Object, calling ``resolvePendingFor`` for each. The pending paint call dispatches to every Component subtype instantiated so far — Form, Container, Component (themselves) — and Form's / Container's / Component's paint methods are enqueued. 3. Later, when the Picker shows its lightweight popup, Spinner3D instantiates the anonymous ``new Scene() { ... }`` subclass, which marks ``Spinner3D$1`` and (recursively) Scene instantiated. The recursion stops at Container — already in ``instantiated`` — and ``resolvePendingFor`` only runs for Spinner3D$1, Scene, and Container. None of those keys hold ``VirtualCall(Component, paint, ...)``; that call is keyed under ``Component`` and never re-fires. 4. With Scene.paint dropped, the runtime's ``resolveVirtual`` walks Spinner3D$1 → Scene → Container, finds Container.paint first, runs Container's default paint (just iterates child Components). The override that calls ``root.render(g)`` to drive the scene-graph paint never fires, and ``SpinnerNode``'s own ``render`` / ``layoutChildren`` overrides — also dropped transitively because ``Node.render`` itself was no longer reachable — never paint the rolling rows. The picker shows the dialog header + Cancel/Today/Done + custom buttons but the spinner column is blank where the date wheel should be. Fix: walk the full transitive ancestor chain on every ``markClassInstantiated`` call (not just direct supertypes) and ``resolvePendingFor`` each, so every previously-recorded pending call whose receiver type is now a supertype of the new class re-dispatches with the new class as a candidate. Pending lists are snapshot per-call so re-entrant additions don't break iteration. After fix the bundle keeps Scene.paint, Node.render / renderChildren / layoutChildren / layoutChildrenInternal / getPaintingRect, plus SpinnerNode.render / layoutChildren / calcRowHeight / calcViewportHeight / calculateRotationForChild / getMin/MaxVisibleIndex / getOrCreateChild — i.e. the full scene-graph rendering path the LightweightPicker baseline relies on.

For ordinary objects that's correct — ``obj.__classDef.methods[mid]`` is the target's own virtual table. A Class instance carries ``__classDef`` pointing at the REPRESENTED class's def: every classObject is built as def.classObject = { __class: "java_lang_Class", __classDef: def, // ← represented class __isClassObject: true, ... }; so ``getName`` / ``getSimpleName`` / static-field access through ``__classDef`` keep working without an extra hop. But VIRTUAL method dispatch on a Class instance MUST resolve against ``java.lang.Class``'s method table, not the represented class's. The pre-existing ``jvm.resolveVirtual(target.__class, mid)`` slow path used ``target.__class`` (always ``"java_lang_Class"`` on a classObject) and would have done the right thing — but the fast-path that runs first short-circuits with the represented class's methods. Concrete fail: ``Double.equals(obj)`` does obj.getClass().equals(Double.class) The ``.equals(Double.class)`` cn1_iv1 hits ``cn1_ivResolve`` with target = ``obj.getClass()`` (a Class instance). The fast-path reads ``target.__classDef`` — Double's def — and returns Double.equals (Double.m: has the ``cn1_s_equals_*`` slot). Double.equals re-runs the same ``getClass().equals(...)`` chain on its own this, recurses into itself, and JS overflows the stack with ``RangeError: Maximum call stack size exceeded`` — the symptom that surfaced ValidatorLightweightPicker after the RTA fix landed (and Double's equals path actually started getting exercised by the picker render chain). Fix: short-circuit the fast-path on classObjects (``__isClassObject === true``). Look up the dispatch id against ``jvm.classes[target.__class]`` — i.e. the java.lang.Class def — which is where Class.equals / Class.hashCode / Class.toString actually live.

The previous patch inlined the class-object check into ``const classDef = ...`` which broke the ``runtime.contains("const classDef = target.__classDef;")`` and ``runtime.contains("classDef && classDef.methods ? classDef.methods [mid]")`` assertions at line 100. Move the short-circuit to its own ``if (target.__isClassObject) { return jvm.resolveVirtual( target.__class, mid); }`` early-return BEFORE the fast path so the literal source pattern is preserved verbatim. Same runtime behaviour, test happy. (2) ``isJsoBridgeClass`` walks ``jsoRegistry.classPrefixes`` doing ``className.indexOf(prefix) === 0``. The prefix list is populated by port.js's IIFE: jsoRegistry.classPrefixes.push( "com_codename1_html5_js_", "com_codename1_impl_html5_JSOImplementations_" ); Both literals match the mangler's ``com_codename1_[A-Za-z0-9_]+`` identifier regex (the trailing underscore is part of the match). Without an explicit ``EXCLUDE`` entry, they get mangled to ``\$c9H`` / ``\$c9I`` and the runtime check no longer matches any actual class name — every JSO bridge dispatch falls through to the ``Missing virtual method`` throw instead of ``createJsoBridgeMethod``. This is what was killing Initializr's boot at the first ``Canvas.getStyle()`` call (``Missing virtual method cn1_s_getStyle_R_com_codename1_html5_js_dom_CSSStyleDeclaration on com_codename1_html5_js_dom_HTMLCanvasElement``). Add both prefix literals to ``EXCLUDE`` so the mangle pass leaves them as the unmangled prefix strings the runtime expects. Verified locally: a fresh ``ENABLE_JS_IDENT_MANGLING=1`` build of HelloCodenameOne now emits ``classPrefixes.push("com_codename1_ html5_js_", "com_codename1_impl_html5_JSOImplementations_")`` verbatim.

The runtime has a fallback that converts that form to the sig-based ``cn1_s__`` key actually used in each class's ``m:{}`` table — but the conversion only fires while the methodId still STARTS with ``cn1_``. Once the mangle pass renames the literal to ``$X``, the conversion silently no-ops and the lookup misses. Concrete failure: Initializr boots, ``HTML5Implementation``'s RAF shim resolves and on the first frame calls spawnVirtualCallback(handler, "cn1_com_codename1_impl_html5_JavaScriptAnimationFrameCallback_onAnimationFrame_double", ...); The literal mangles to ``$aEs``; the ``JavaScriptAnimationFrameCallback`` class def has ``m: { cn1_s_onAnimationFrame_double: cn1_..._onAnimationFrame_double }`` where the m: KEY mangles independently to a different symbol. The runtime's resolveVirtual walks the hierarchy, ``$aEs`` is not in the table, the legacy→sig conversion at line 836 is gated on ``methodId.indexOf("cn1_") === 0`` and ``$aEs`` doesn't satisfy it, the throw fires: ``Missing virtual method $aEs on $a6J``. Initializr never gets past host-callback id=67. Fix: rewrite the affected port.js literals (and the methodId constants that flow into ``jvm.resolveVirtual``) from the class-specific form to the sig-based form. Both port.js and the class def's ``m:`` map now reference the same source string, so the mangler renames them in lockstep and the dispatch matches. Touched constants (resolveVirtual targets only — bindNative constants and ``global[ctorName]`` lookups still use the legacy form because their respective runtime helpers handle both): containerFindFirstFocusable / formGetActualPane / formSetFocused / displayShouldRenderSelection / formLayoutContainer / containerSetLayout / formSetTitle / baseTestPrepare / baseTestRunTest / baseTestFail / baseTestDone / initMethodId2 Plus inline literals: AnimationFrameCallback.onAnimationFrame (both browser + Impl variants), Throwable.toString / getMessage / printStackTrace, Runnable.run (3 sites), EventListener.handleEvent, BaseTest.isDone.

The DOM convention treats EventListener as a SAM (single abstract method) interface — a plain function IS the handler — and the same shape applies to Runnable.run, AnimationFrameCallback.onAnimationFrame, SuccessCallback.onSuccess, etc. When the wrapped value is a function and no ``[member]`` lookup matches, fall back to invoking the receiver itself with the dispatch's args. Mirror change on both sides: ``invokeJsoBridge`` in parparvm_runtime (worker-side direct dispatch when there's no host bridge) and ``__cn1_jso_bridge__``'s host-side handler in browser_bridge.js (main-thread dispatch when the worker forwarded the call). This was the residual block on Initializr's boot after the sig-based dispatch fix (98181dc83): ``HTML5BrowserComponent`` instals a ``submit`` listener whose handler comes back through the worker as a JSO ``EventListener.handleEvent`` call, the JSO bridge finds ``cn1_s_handleEvent_*`` is not on the wrapped function's own properties, and threw before reaching user code.

Hand-written ``port.js`` dispatch sites (``__nativeEventListener.handleEvent``, ``AnimationFrameCallback.onAnimationFrame``, ...) are invisible to bytecode-only RTA, so anonymous ``EventListener`` impls were getting culled and the runtime threw "Missing JS member handleEvent" the moment the DOM fired. Seeding the interface methods as pending virtual calls keeps the impl methods in the m: map of every instantiated implementing class. - Same file: detect ``NativeLookup.register(stub.class, impl.class)`` invocations and mark the LDC class operands as instantiated. ``NativeLookup.create()`` instantiates the impl class via ``Class.newInstance()`` reflection — invisible to RTA. Without this, every method on a registered impl gets culled and the framework throws "Missing virtual method" the first time it dispatches into the native interface. - ``CodenameOneImplementation.initImpl``: handle main classes with no package prefix. After mangling the class-name LITERAL in ``classDef.name`` is a short ``$abc`` token with no underscores, so ``getName()`` returns it unchanged and ``lastIndexOf('.')`` returns -1. The previous unconditional ``substring(0, -1)`` then threw a cryptic AIOBE("0") deep inside ``Display.init``. - Build scripts: switch from ``esbuild --minify`` to ``--minify-syntax --minify-whitespace``. The bundled ``--minify-identifiers`` renames top-level bindings on a per-file basis, but worker-side files share global scope via ``importScripts`` — renaming a top-level function in one file orphans every cross-file reference. - Runtime: when ``fail()`` sees a Java throwable with no JS ``.stack``, fall back to the ``CN1_THROWABLE_STACK`` field that ``fillInStack`` populates. No-op when ``fillInStack`` isn't called by the throwable's ctor (current default), but materializes a readable stack the moment any code chooses to call it.

RTA runs after the graph-based pass and has strictly more information (it honours the instantiated set + the JSO bridge interface seeds), so anonymous SAM impls like ``LocalForage$1.callback`` for an ``impl.setItem(key, val, new SetItemCallback() {})`` call need to be resurrected — the legacy pass dropped them because nothing in bytecode invokes ``callback`` directly, but the host bridge invokes them at runtime via the seeded pending dispatch on ``SetItemCallback``. Without un-eliminating, the impl method stays dropped, ``done.notifyAll()`` never fires, and the calling Java thread deadlocks on ``done.wait()``. - ``mangle-javascript-port-identifiers.py``: detect JSO bridge classes by walking the ``i:[...]`` (interfaces) + ``b:"..."`` (baseClass) graph the translator emits per classdef, instead of scanning for the now-rarely-emitted ``a:{}`` block. The structural-optimization landing made ``defineClass`` auto-populate ``assignableTo`` from ``baseClass + interfaces`` and stop emitting ``a:{}``, so the marker walk silently missed every JSO bridge class outside the ``com_codename1_html5_js_*`` / ``com_codename1_impl_html5_JSOImplementations_*`` prefix list. Classes like ``com_codename1_teavm_ext_localforage_LocalForage_LocalForageImpl`` got mangled to ``$doA``, the JSO bridge wrapped the host result with ``__class = unmangled``, ``resolveVirtual`` couldn't find the registered (mangled) classdef, and the runtime threw ``missing_receiver`` on the next dispatch. Also limit the per-class scan window to the next ``_Z({`` boundary so the regex doesn't pick up interface lists from neighbouring classdefs. - ``parparvm_runtime.js``: generic SAM-functor handler in ``toHostTransferArg``. CN1 Java callback wrappers (no ``__cn1HostRef``, no ``__jsValue`` — just ``__classDef`` / ``__class``) being passed as a host-bridge argument used to fall through to plain ``Object.keys`` iteration, which serialised the shared mutable classdef graph and detonated with ``RangeError: Maximum call stack size exceeded`` deep in the LocalForage init path. Instead, recognise SAM JSO impls by inspecting the impl class's ``m:`` map (filtered to skip ``__INIT__`` / ``__CLINIT__``) — once RTA un-elimination keeps the SAM method alive, the m: lookup recovers the dispatch id, we mint a worker callback that dispatches the SAM and return a callback marker. Same shape as the existing ``EventListener`` / ``AnimationFrameCallback`` ``nativeArgConverters`` in port.js, just generalised. Also skip ``__class`` / ``__classDef`` / ``__id`` / ``__monitor`` / ``__jsValue`` / ``__cn1WorkerCallbackId`` keys in the object iteration fallback — these are CN1-internal bookkeeping the host doesn't read. - ``localforage-shim.js`` (new) + ``index.html``: ship a minimal localStorage-backed ``window.localforage`` plus a ``window.createConfigOptions`` factory that returns ``{}``. The Java-side ``LocalForage`` wrapper expects both globals to exist (TeaVM's ``@JSBody`` annotations would have generated them at translation time, but the new ParparVM JS pipeline doesn't process ``@JSBody``); without these the JSO bridge throws ``Missing JS member createConfigOptions`` the first time ``Storage.getInstance()`` / ``FileSystemStorage.getInstance().openOutputStream(...)`` runs.

JSO bridge methods are dispatched from the HOST (JS), not via bytecode call sites the scan sees, so SAM impls like ``LocalForage$1.callback`` were skipped from m: even after RTA un-elimination kept the function body alive. Result: the host-bridge worker-callback flow couldn't resolve the SAM (no m: entry → ``resolveVirtual`` falls through to the JSO bridge fallback which has no impl), the calling Java thread waited on ``done.notifyAll()`` that never fired, and the lifecycle test hung at ``cn1Started=false`` with no surfaced error. Fix: after building ``referencedDispatchIds`` from the bytecode scan, also tag every non-static, non-init/clinit method on a JSO bridge type (transitively assignable to ``com_codename1_html5_js_JSObject``) so the m: entry survives. The actual function body is already kept by RTA un-elimination, this just makes the dispatch table register the entry too.

The check was meant to recover setters from the dispatch id alone (Java doesn't emit the @JSProperty annotation into the runtime), but it also matched genuine multi-arg methods that happen to start with ``set`` — most visibly ``LocalForage.setItem(key, value, callback)``. The bridge then tried ``localforage.item = arg[0]`` (setter for ``item``) instead of ``localforage.setItem(...)``, no value got stored, the SAM callback was never invoked, and the calling Java thread deadlocked on ``done.wait()`` forever. The lifecycle test reproduced as a hang at host-callback id=84 with no surfaced error — Initializr stuck on "Loading...". Two reinforcing fixes: - Require ``returnClass == null`` for the setter shortcut. True setters return ``void``; methods that return a value are never classified as setters even when they happen to start with ``set``. - Explicit deny-list for the common false positives: ``setAttribute`` / ``setProperty`` (existing) plus the ``LocalForage`` config + setItem / setDriver / setStoreName / setVersion / setSize / setDescription methods. With this fix the mangled+minified Initializr bundle reaches ``cn1Started=true`` end-to-end (matching the unmangled debug bundle).

Approach: count the number of parameter-type-start prefixes (``_java_`` / ``_com_`` / ``_org_`` / ``_kotlin_`` / ``_sun_`` / ``_javax_``) in the dispatch id's argument section. A real ``@JSProperty void setX(X)`` setter has exactly one parameter type prefix; multi-arg methods like ``setSelectionRange(int, int)`` / ``setItem(String, JSObject, SetItemCallback)`` / ``setRequestHeader(String, String)`` have two or more. Two or more hits forces ``method`` regardless of name shape. Static deny-list extended to cover the common DOM / ``XMLHttpRequest`` cases the type-prefix heuristic can't catch (primitive-only signatures like ``setTimeout(Object, int)``).

The build scripts only relocate a hand-picked allowlist (``material-design-font.ttf``); everything else stays at the root, but ``HTML5Implementation.getResourceAsStream`` blindly prepends ``assets/`` for non-icon.png lookups. That's why ``ResourceBundle.getResourceAsStream("/messages_xx.properties")`` in ``TemplatePreviewPanel.loadBundleProperties`` returned null on every probed path — the .properties files exist at the bundle root, not under ``assets/``. ``loadBundle`` then logged the error via ``Log.e`` and tried the next candidate, producing the ``Exception: null`` flood the user spotted (the throwables were ``IOException(null)`` instances cn1's JS-port stringifyThrowable renders as ``null``). Same root cause for ``cn1-version-numbers`` and other CN1 metadata files. Fix: try ``assets/`` first (preserves the existing behaviour for resources the build scripts deliberately move there), then fall back to the bundle root before giving up. The fallback is a no-op when the resource is in ``assets/``; for the .properties + metadata files emitted at the root, it makes the lookup actually return the bytes.

After mangling, the legacy class-specific names (``cn1_java_lang_Object_ hashCode_R_int`` and friends) become opaque ``$aaw``-style symbols that resolveVirtual's prefix-strip remap doesn't recognise — so runtime callers that still passed those names silently fell through to the bound ``Object.hashCode`` (identity hash) and ``Object.equals`` (reference equality), corrupting every HashMap that used String keys (e.g. ``CSSBorder.STYLE_MAP``). That manifested as repeated ``Unsupported border style solid`` floods through ``Log.e`` — masquerading as the ``Exception: null`` log spam because the Log.e fallback wrapped a static method with an instance-style ``(__cn1ThisObject, throwable)`` signature, shifting ``throwable`` to ``undefined`` and ``stringifyThrowable`` printing ``"null"``. Switch the runtime ``equals`` / ``toString`` / HashMap-fallback hash dispatches to the shared ``cn1_s_*`` ids; tag the array-clone regex helper with a ``CN1_CLONE_DISPATCH_ID`` constant (regex bodies aren't mangled, so an opaque ``$Yj`` clone id never matched the literal pattern); fix the ``Log.e`` fallback signature so real exceptions surface; and route ``HTML5Implementation.hideSplash`` through a new ``__cn1_hide_splash__`` host handler so the worker no longer hits a ``jQuery is not defined`` ReferenceError when removing the splash. With these in place the Initializr bundle boots clean (0 exceptions) and renders the actual UI under the new JS port.

Trouble is ``printStackTrace`` ultimately routes through ``System.out`` → ``NSLogOutputStream`` → ``jvm.log`` → vmMessage LOG, which the main thread surfaces *asynchronously*; by the time it lands the console.error from Log.e has already printed and there's no way to correlate the trace with the throw. Worse, in the deployed production preview those LOG messages never came through at all, so the user only ever saw ``Exception: $iH | $iH | stack=printed`` with zero frames. Inline the cached stack instead. ``Throwable.fillInStack`` is *meant* to populate ``cn1_java_lang_Throwable_stack`` with ``new Error().stack``, but the Codename One Throwable constructors don't actually invoke it (every other Java port lazy-fills via their ``printStackTrace`` native), so worker-side throwables almost always arrive at Log.e with the field unset. Read it when present; otherwise fall back to a fresh ``new Error().stack`` captured at the Log.e call site — that frame list points to the catch block one level above ``Log.e`` and is enough to triage where the exception was caught and handed to ``Log.e``. Without this every exception line collapses to ``Exception: | `` with no frames.

The reason is two-layered: the original event-handler NPE is caught by ``Display.mainEDTLoop``, which fires registered EDT error handlers; one of those is the anonymous ActionListener ``Log.bindCrashProtection`` registers, and *that listener* throws a second NPE while trying to format the report (somewhere in the ``Display.getInstance().getProperty(...)`` / ``Display.getInstance().getPlatformName()`` / ``(Throwable) evt.getSource()`` chain on lines 394–402). The formatting NPE is what lands in the user's console; the original event-handler exception silently disappears. Without seeing the original we can't fix the underlying broken event path. Wrap each step of the listener in its own try/catch with a tagged ``[edtErr] ...`` System.out.println so we can identify which call fails on the live deploy. Replace the unchecked ``(Throwable) evt.getSource()`` cast with an ``instanceof`` guard so non-Throwable sources don't blow up the whole reporter — the original Throwable still reaches ``Log.e`` along the working path. Marked TEMPORARY in the comment; remove the granular wrapping once the JS-port root cause is fixed. Also drop the giant ``captured-at-Log.e-stack=...`` dump the ``stringifyThrowable`` fallback in port.js was emitting on every Log.e call. It served its purpose (it identified the bind-crash- protection chain), but with the targeted instrumentation now in ``Log.bindCrashProtection`` we don't need to ship every Log.e caller's full JS frame list any more.

The ``Exception: $iH`` lines we keep seeing actually come from ``Display.mainEDTLoop``'s outer ``catch (Throwable err) { Log.e(err); }`` at ``Display.java:1033`` and ``:1077``. The reason those Log.e calls render as bare ``Exception: `` with no stack info is that the Codename One ``Throwable`` constructors don't invoke ``fillInStack`` themselves — every other Java port lazy-fills via ``printStackTrace``'s native. So worker-side throwables arrive at every catch handler with the ``stack`` field still null. Capture ``new Error().stack`` directly in ``jvm.newObject`` whenever the class is assignable to ``java.lang.Throwable``. That covers both the runtime's ``createException`` path (NPE / ClassCastException thrown by ``cn1_iv*`` virtual dispatch helpers) and translated ``throw new Foo(...)`` bytecode paths uniformly — every Throwable now arrives at its catch site with a populated ``stack`` field. The existing ``stringifyThrowable`` reader in port.js already prints ``stack=`` whenever the field is set, so Log.e output now includes the throw-site frame list.

The full chain (now visible in the live preview's stack via the previous commit) is: Form.pointerDragged → Form.getActualPane(formLayeredPane, x, y) → formLayeredPane.getResponderAt(x, y) → Component.contains(x, y) → Component.getAbsoluteX() → Component.getX() → throw NPE on bounds.getX() ``bounds`` is declared ``private final Rectangle bounds = new Rectangle(0, 0, new Dimension(0, 0));`` so it shouldn't *ever* be null after Component. runs. Yet on the live preview it is — suggesting some Component subclass's constructor chain isn't reaching Component.'s field initializer (likely an anonymous-inner-class translation issue or RTA pruning gap on the JS port). Two-part defensive fix: 1. Guard ``bounds == null`` in the four bound-reading getters (``getX``, ``getY``, ``getWidth``, ``getHeight``). Returning 0 keeps ``Component.contains`` / ``getAbsoluteX`` / hit-testing alive so user input flows again instead of every click NPEing out of the EDT. 2. ``reportNullBounds`` logs the offending class name once per ``#`` pair via ``Log.p(s, 1)`` — that's the unconditional ``console.error`` path on the JS port (the ``System.out.println`` path is gated behind ``?parparDiag=1`` and gets dropped on the live preview). Once we see the class name we can fix the underlying construction path and remove this whole patch. Marked TEMPORARY in the comments so we remember to peel it off once the root cause is fixed.

After the post-translation identifier mangler runs: * ``def.name`` is the *mangled* short class symbol (e.g. ``$cm`` for MenuBar — registered on the classDef as the ``n:`` field). * The actual ``cn1____INIT__`` global is *also* mangled, but to a completely different short symbol (e.g. ``$bq``). Neither short symbol bears any prefix-tail relationship to the other, so ``global["cn1_$cm___INIT__"]`` is undefined for every class in the bundle. ``Class.newInstance()`` and ``jvm.createException()`` both silently fall through, returning an object whose constructor never ran. That's fatal for any class whose Java field initializers must execute — ``Component``'s ``private final Rectangle bounds = new Rectangle(0, 0, ...);`` is the canonical case. Every reflectively-constructed Component subclass (notably ``laf.getMenuBarClass().newInstance()`` from ``Form.installMenuBar``) arrives with ``bounds == null`` and trips an NPE the first time pointer-event hit-testing reaches ``getX()``. The user-visible symptom on the live preview was every click silently disappearing into ``Display.mainEDTLoop``'s ``catch (Throwable)``. Translator side --------------- Find each class's surviving no-arg ```` and emit a direct function reference under ``t:`` inside the ``_Z({...})`` payload — same shape as the existing ``c:`` clinit attachment. Skip when the ctor is eliminated / abstract / native, or when the class has no no-arg ```` at all (interfaces, abstract roots, classes whose only constructor takes args). Runtime side ------------ ``defineClass`` extracts ``def.t`` to ``def.noArgCtor``. ``Class.newInstanceImpl`` and ``jvm.createException`` now prefer ``def.noArgCtor`` and only fall back to the legacy global lookup when the new field is absent — keeps any pre-existing class registrations that haven't been re-translated against the new emitter shape working as a no-op (matching prior behaviour).

With trace hooks wired through cls.methods (rewireDispatchTables) the test confirms: 1. After Dialog.show opens the modal, the click at the OK button's canvas position DOES reach the worker — Form.pointerReleased fires at (1148, 910), the DPR-2-scaled OK position. 2. The form receiving the click is the BACKGROUND Form ($av, identity r42590), NOT the Dialog ($Z). So Display.handleEvent's getCurrentUpcomingForm(true) returns impl.getCurrentForm() and gets back the background form rather than the dialog. The OK button never gets the click. Either Display.setCurrent(dialog, ...) was never called, or impl.currentForm got reset back to the background after. Wrapping Display.setCurrent / Form.show / Form.showModal to confirm breaks boot (those yield during init and the wrap upsets the scheduler), so the diagnostic stops short of identifying which of the two paths caused this. Also adds test-deployed-initializr.mjs which drives the deployed iframe — currently the bundle never reaches "ready" under headless Chromium, so the test isn't useful yet but is parked for when the bundle's headless path settles.

Display.animationQueue also stays null throughout (no transition was queued for the dialog either). So the Dialog.show flow is reaching Display.setCurrent but neither setCurrentForm nor initTransition is firing for the dialog. The two paths that should hit setCurrentForm in Display.setCurrent are: - line 1621: if (!transitionExists && animationQueue empty) setCurrentForm(newForm) - line 1573: animationQueue last-entry transition destination Both should be reachable here. Next step: instrument Display.setCurrent to confirm whether it's even being called for the dialog (vs. early- returning via the SHOW_DURING_EDIT_IGNORE branch or the !isEdt path).

Form.showModal(int...) now explicitly sets the modal dialog as the impl's currentForm immediately after Display.setCurrent(this, reverse). On the JS port, virtual-dispatch RTA appears to prune the Display.setCurrent → setCurrentForm helper → impl.setCurrentForm chain (callers of Display.setCurrent show 0 occurrences in the translated_app.js bundle even though the bytecode emits the call, and a 200ms poll of impl.currentForm shows it never updates from the background Form to the dialog). Routing pointer events depends on impl.getCurrentForm() — when that stays as the background form, the dialog renders but every tap on its OK button hits the form underneath instead. Forcing impl.setCurrentForm(this) here makes the dispatch route to the dialog the moment showModal queues the modal block. No-op on every other port. 2. CodenameOneImplementation.initImpl wraps the m.getClass().getName() / lastIndexOf / substring trio in try/catch. The JS port surfaces an ArrayIndexOutOfBoundsException there during boot — apparently from getName() returning a value that lastIndexOf can't reconcile with substring. Failing the whole bootstrap to skip a packageName lookup is wrong; default to "" if anything throws. Reproducer: scripts/test-initializr-interaction.mjs prints "Test 1: OK click did NOT dismiss the dialog" before this fix and its currentForm-poll output shows currentForm flipping null → background Form once at boot and never to the Dialog.

The skips were added in 4c11ff5fb and be4f0e433 with the rationale that transition grids would overflow the browser-lifetime budget; running them locally shows that's no longer the bottleneck. Findings (local Playwright run on 24MB bundle, 840s budget): - 14/17 animation tests reach runTest, render, and emit a PNG via the CN1SS chunk stream — i.e. AnimationTime + Motion + transition pipeline all execute end-to-end on the JS port. - 3 tests time out waiting for done(): FadeTransitionTest, ComponentReplaceFadeScreenshotTest, ComponentReplaceSlideScreenshotTest. Two of those (Fade/ComponentReplaceFade) emit png_bytes successfully before timing out, so done() chain is what's missing - not rendering. ComponentReplaceSlide never emits at all - it hangs before screenshot capture. - ComponentReplaceFadeScreenshotTest png_bytes=73166 and ComponentReplaceFlipScreenshotTest png_bytes=73166 are byte-for-byte identical, which is statistically near-impossible if Fade and Flip rendered different visual content. Strong indicator that ComponentReplace transitions on the JS port skip animation frames and fall back to a static "from" snapshot for both transition types. - The chunk decode failures (Cn1ssChunkTools "Failed to extract/decode CN1SS payload") are the same pre-existing jsChunkDrop issue that affects every screenshot test on JS - chunks dropped under console.log line truncation. Not specific to animations. These are diagnostic enables. The ComponentReplace identical-byte-count and Slide-hangs findings deserve their own follow-up; the chunk-drop and done()-not-firing issues are pre-existing JS port-wide problems.

The intent (per the inline comment at port.js:4312) is that Display.screenshot() in the worker reads from OffscreenCanvas which may not reflect the main-thread visible canvas, so substituting a host capture is the right call for those tests. But the animation/transition screenshot suite (and AbstractComponentReplace ScreenshotTest) doesn't go through Display.screenshot() at all — those tests construct a 6-cell grid into an off-screen Image.createImage(...) mutable buffer (see AbstractAnimationScreenshotTest.buildGrid) and pass that Image straight to emitImage. The hijack fires anyway, throws the correct grid PNG away, and substitutes whatever the visible canvas happens to be showing. The result on the JS port: - FadeTransitionTest and FlipTransitionTest emitted byte-identical PNGs because both captured the same stale visible canvas (settleSig=df09be45, settleChanged=0). - ComponentReplaceFade, ComponentReplaceSlide, ComponentReplaceFlip all emitted byte-identical PNGs for the same reason. - ComponentReplaceSlide previously timed out entirely while the host capture's 24-attempt × 48-frame settle loop chewed past the runner's per-test 10s deadline. Add an emitImageDirect / emitChannelDirect pair that does the same work as emitImage / emitChannel but with different method IDs, so the JS port fallback (which is bound by method ID) doesn't bind to them. Switch AbstractAnimationScreenshotTest.captureAndEmit to use the direct path so the buildGrid / buildScreenshot Image bytes reach the chunk stream verbatim. emitCurrentFormScreenshot still uses the hijacked emitChannel so other screenshot tests that go through Display.screenshot() keep benefiting from the OffscreenCanvas-staleness workaround. Validation locally with the full hellocodenameone JS port bundle: - FadeTransitionTest now distinct from FlipTransitionTest (sha 0fc774d0 vs 61e4eeea, was f5c96fa3 for both). - ComponentReplaceSlide distinct from Fade/Flip (sha 98fb8ed5 vs 6f820a22, was fbe42beb for all three). - All three tests reach done() within the per-test deadline; no more "timeout waiting for DONE" errors for any animation/transition test. ComponentReplaceFade and ComponentReplaceFlip remain byte-identical (73166 bytes both) because of a separate underlying bug: the Fade and Flip transitions on the JS port don't actually paint a visible overlay in the off-screen Image, so both fall through to "all middle frames show the Source card". That's a transition-rendering issue, not an emission issue — separate follow-up.

After the rebuild, `lambda2RunBridge` (the awaitTestCompletion poll lambda) was firing once, hitting `missingDispatch=1` because `resolveCn1ssRunnerTranslatedMethod([cn1ssRunnerAwaitLambda3MethodId])` returned null, and silently bailing out — `CN.setTimeout`'s 50ms poll loop never rescheduled, `isDone()` was never checked, and every test that goes through the standard onShowCompleted→done() path (SlideHorizontalTransitionTest, all subsequent animation tests) hung until the suite timed out at 600s. Smoking gun in the browser log: lambda3RunBridge:dispatch:index=1:nextIndex=2 (MainScreen finalized) lambda2RunBridge:HIT (Slide poll fires once) lambda2RunBridge:missingDispatch=1 (lookup fails, polling dies) Build the candidate-id list by looping 0..15 over the lambda index so the lookup keeps working when the translator renumbers. Apply the same pattern to the finalizeLambda string-receiver-bypass shim. Verification: full hellocodenameone JS port suite now reaches all 80 DEFAULT_TEST_CLASSES entries (was 3 before fix), emits CN1SS:SUITE: FINISHED, and produces the 17 animation/transition test PNGs that the Apr 26 build never reached.

The prior path was: 1. allocate a worker-side `Uint8ClampedArray arr` 2. unpack rgb int[] into arr (R, G, B, A bytes) 3. `ImageData d = ctx.createImageData(w, h)` 4. `((Uint8ClampedArraySetter)d.getData()).set(arr)` 5. `putImageData(canvas, d)` Step 4 is silently broken across the worker→host bridge. The host-side `hostResult` in browser_bridge.js (~line 485) clones any returned `Uint8ClampedArray` into a fresh worker-local view to avoid per-element host RPC on large reads (`get(index)` loops, e.g. RGBImage.getRGB). That optimization makes `d.getData()` return a *clone*, not a live reference — `set(arr)` on the clone writes only to the worker copy, the live `host_imageData.data` stays zero-initialised, and step 5 puts transparent black onto the canvas. Net effect: `CommonTransitions`' rgbBuffer fade fast path (per-pixel-alpha mutation + drawImage) draws nothing for intermediate positions. `FadeTransitionTest` cells F2-F5 came out as pure source, F1/F6 happened to bypass the path so they were correct. Same root cause for `ComponentReplaceFadeScreenshotTest` — byte-identical to the Flip output (73166 bytes both) because both fell through to "all middle frames are the source card." Diagnosis chain (all from the running suite, no debugger needed): - DIAG_RGB confirmed paintAlpha's per-pixel mutation reached drawRGB with the right alpha bytes (57, 105, 150, 198 for F2-F5). - DIAG_DI showed every drawImage call ran at globalAlpha=1.0 with source-over, as expected. - DIAG_CID readback caught the bug: cached_dData.set(arr) → cached shows alpha=57 (wrote to clone) d.getData() again → fresh view shows 0 (live buffer still empty) sameRef=false (each getData() call clones independently) Fix: skip the round-trip. Add `ImageData.writeArgbBuffer(int[], offset, w, h)`, backed by a host-side prototype extension installed in browser_bridge.js. The int[] structured-clones to host in one postMessage, the host unpacks ARGB → RGBA directly into `this.data` (live buffer there), and putImageData sees the right pixels. Verification on the full hellocodenameone JS port suite: - FadeTransitionTest cells now show progressive blends: F1 (31,64,104) → F2 (59,56,87) → F3 (82,50,73) → F4 (105,43,60) → F5 (128,37,46) → F6 (156,29,29) - Linear ramp matches `src*(1-α) + dst*α` per the position values. - ComponentReplaceFadeScreenshotTest now distinct from Flip (99848 bytes vs 73166, was 73166 for both). Performance: `writeArgbBuffer` does the same per-pixel work the old `writeArgbToRgba` PixelWriter did, just on the host side instead of through the JSO bridge. Each `arr.set(int, int)` previously routed through the indexed-set worker fast path (no host RPC), so latency is unchanged — the overall path is now one structured clone of the int[] plus a host-local 4-byte-per-pixel unpack, vs. the prior worker-side allocation + 4-write-per-pixel + cross-boundary `set(arr)` that wrote into a phantom buffer.

On every other port ``Display.setCurrent`` updates ``impl.currentForm`` synchronously, so the explicit assignment here is a no-op there. The guard around modal-only + non-null impl keeps it scoped narrowly enough that it can't accidentally fire for non-dialog form transitions.

Wraps Container.getComponentAt(int, int) and Form.getResponderAt(int, int) with postFn(args, return-value) hooks. Each pointer-press triggers a recursive walk through the form hierarchy; capturing the return value at each frame tells us exactly which component was identified as the click target. The wrapFn helper is updated to pass the return value to postFn so this works for any future return-value-dependent diagnostic. 2. Logs raw window-level mousedown / mouseup / pointerdown / pointerup / click / mouseout / pointerout / mouseleave events at the DOM level. Compared against the worker-side Form.pointerPressed / pointerReleased trace, this isolates the layer that drops events. Concrete finding from running the instrumented test against the current locally-served Initializr bundle (no fix yet — diagnostic only): - DOM events fire correctly for every click (mousedown, mouseup, click all reach #cn1-peers-container). - Form.getResponderAt at the Hello-button click position correctly returns the helloButton (`$at#0rvngb`). - BUT only ~50% of click halves dispatch on the worker: * Hello click @ (1872,282 native): Form.pointerPressed fires; matching Form.pointerReleased never fires. * Subsequent OK click @ (1148,910): Form.pointerReleased fires; matching Form.pointerPressed never fires. - The pattern is consistent with onMouseDown/onMouseUp's mouseDown state getting out-of-sync between the dual-registered listeners (mousedown + pointerdown share onMouseDown; mouseup + pointerup + mouseout + pointerout share onMouseUp; see JavaScriptEventWiring). shouldIgnoreMousePress / `!isMouseDown()` early-returns are intended to dedupe the doubled events but appear to drop one half of each user-level click on the local serve. Next step (separate commit/PR): figure out the dedup ordering. Likely needs an event-id check rather than a stateful mouseDown flag, or register only `pointerdown`/`pointerup` (modern) OR only `mousedown`/ `mouseup` (legacy) — not both.

Modern browsers fire BOTH the pointer event AND a synthesized mouse follow-up for every real click (per spec), so the listener was being called twice per click. ``HTML5Implementation.onMouseDown`` / ``onMouseUp`` try to dedupe via a stateful ``mouseDown`` flag (``shouldIgnoreMousePress`` early-return on the second mousedown, ``!isMouseDown()`` early-return on the second mouseup), but on the locally-served bundle Test 2 was visibly affected: drag interactions spuriously left transparent holes in the canvas, and Test 1's first clicks showed asymmetric press/release routing. Registering only pointer events (every browser the JS port targets — Chrome 55+, Edge, Firefox 59+, Safari 13+ — supports them) eliminates the double-fire. Add ``pointercancel`` to keep the equivalent of the old ``mouseout`` side-channel for click-aborted recovery. Verification: the same instrumented test (``test-initializr- interaction.mjs``, with the ``Container.getComponentAt`` return-value hook from 5b90da164) now shows Test 2 drag interactions producing matched press+release pairs that they didn't before. Caveat: the Test 1 Dialog OK click still doesn't dismiss the dialog locally — that's a SEPARATE first-click asymmetry where ``Form. pointerReleased`` never reaches the EDT for the Hello-button click even though the DOM ``pointerup`` fires AND ``Container. getComponentAt`` correctly identifies the helloButton at the click position. Cause is somewhere in the worker→EDT dispatch chain (``nativeCallSerially → new Thread → nativeEdt.run``); needs deeper instrumentation in ``onMouseUp`` to confirm whether the listener is being invoked at all for that first click. Documenting here so the next investigation pass starts from the right place.
