Hi all, I'm getting a deadly embrace that happens when the AWT event queue thread tries to get a lock within DefaultDatasetView.getColor and when DefaultStatusService.showStatus on a worker thread tries to publish a synchronous request for status display after taking the DefaultDatasetView's lock in DefaultDatasetView.rebuild. It happens periodically, but it's timing-dependent, so not so reproducible.
The bug is somewhat debatable. Possible candidates: It's a little drastic for DefaultDatasetView.getColor to synchronize on the view itself. Maybe some proxy for the color system could have a synchronizing object. The other candidate is DefaultEventService.showStatus which could use EventService.publishLater - I don't think there's much need for status publishers to wait around for the status to show on the screen. The two stack traces: Thread [AWT-EventQueue-0] (Suspended) DefaultDatasetView.getColor(ChannelCollection) line: 261 Synchronized method on DefaultDatasetView FgColorTool(AbstractColorTool).drawIcon() line: 175 FgColorTool(AbstractColorTool).onEvent(DisplayActivatedEvent) line: 184 NativeMethodAccessorImpl.invoke0(Method, Object, Object[]) line: not available [native method] NativeMethodAccessorImpl.invoke(Object, Object[]) line: 39 DelegatingMethodAccessorImpl.invoke(Object, Object[]) line: 25 Method.invoke(Object, Object...) line: 597 DefaultEventService$ProxySubscriber<E>.onEvent(E) line: 282 DefaultEventService$ProxySubscriber<E>.onEvent(Object) line: 1 DefaultEventBus(ThreadSafeEventService).publish(Object, String, Object, List, List, StackTraceElement[]) line: 971 DefaultEventBus.access$1(DefaultEventBus, Object, String, Object, List, List, StackTraceElement[]) line: 1 DefaultEventBus$1.run() line: 201 DefaultThreadService.invoke(Runnable) line: 91 DefaultEventBus.publishNow(Object, String, Object, List, List, StackTraceElement[]) line: 195 DefaultEventBus.publishNow(Object) line: 86 DefaultEventService.publish(E) line: 95 DefaultDisplayService.setActiveDisplay(Display<?>) line: 129 DefaultDisplayService.onEvent(WinActivatedEvent) line: 247 NativeMethodAccessorImpl.invoke0(Method, Object, Object[]) line: not available [native method] NativeMethodAccessorImpl.invoke(Object, Object[]) line: 39 DelegatingMethodAccessorImpl.invoke(Object, Object[]) line: 25 Method.invoke(Object, Object...) line: 597 DefaultEventService$ProxySubscriber<E>.onEvent(E) line: 282 DefaultEventService$ProxySubscriber<E>.onEvent(Object) line: 1 DefaultEventBus(ThreadSafeEventService).publish(Object, String, Object, List, List, StackTraceElement[]) line: 971 DefaultEventBus.access$1(DefaultEventBus, Object, String, Object, List, List, StackTraceElement[]) line: 1 DefaultEventBus$1.run() line: 201 DefaultThreadService.invoke(Runnable) line: 91 DefaultEventBus.publishNow(Object, String, Object, List, List, StackTraceElement[]) line: 195 DefaultEventBus.publishNow(Object) line: 86 DefaultEventService.publish(E) line: 95 AWTWindowEventDispatcher.windowActivated(WindowEvent) line: 94 SwingDisplayWindow(Window).processWindowEvent(WindowEvent) line: 1877 SwingDisplayWindow(JFrame).processWindowEvent(WindowEvent) line: 274 SwingDisplayWindow(Window).processEvent(AWTEvent) line: 1823 SwingDisplayWindow(Component).dispatchEventImpl(AWTEvent) line: 4630 SwingDisplayWindow(Container).dispatchEventImpl(AWTEvent) line: 2099 SwingDisplayWindow(Window).dispatchEventImpl(AWTEvent) line: 2478 SwingDisplayWindow(Component).dispatchEvent(AWTEvent) line: 4460 DefaultKeyboardFocusManager(KeyboardFocusManager).redispatchEvent(Component, AWTEvent) line: 1850 DefaultKeyboardFocusManager.typeAheadAssertions(Component, AWTEvent) line: 910 DefaultKeyboardFocusManager.dispatchEvent(AWTEvent) line: 409 SwingDisplayWindow(Component).dispatchEventImpl(AWTEvent) line: 4502 SwingDisplayWindow(Container).dispatchEventImpl(AWTEvent) line: 2099 SwingDisplayWindow(Window).dispatchEventImpl(AWTEvent) line: 2478 SwingDisplayWindow(Component).dispatchEvent(AWTEvent) line: 4460 EventQueue.dispatchEvent(AWTEvent) line: 599 DefaultKeyboardFocusManager$DefaultKeyboardFocusManagerSentEvent(SentEvent).dispatch() line: 55 DefaultKeyboardFocusManager$DefaultKeyboardFocusManagerSentEvent.dispatch() line: 183 DefaultKeyboardFocusManager.sendMessage(Component, AWTEvent) line: 210 DefaultKeyboardFocusManager.dispatchEvent(AWTEvent) line: 286 SwingDisplayWindow(Component).dispatchEventImpl(AWTEvent) line: 4502 SwingDisplayWindow(Container).dispatchEventImpl(AWTEvent) line: 2099 SwingDisplayWindow(Window).dispatchEventImpl(AWTEvent) line: 2478 SwingDisplayWindow(Component).dispatchEvent(AWTEvent) line: 4460 EventQueue.dispatchEvent(AWTEvent) line: 599 SequencedEvent.dispatch() line: 101 EventQueue.dispatchEvent(AWTEvent) line: 597 EventDispatchThread.pumpOneEventForFilters(int) line: 269 EventDispatchThread.pumpEventsForFilter(int, Conditional, EventFilter) line: 184 EventDispatchThread.pumpEventsForHierarchy(int, Conditional, Component) line: 174 EventDispatchThread.pumpEvents(int, Conditional) line: 169 EventDispatchThread.pumpEvents(Conditional) line: 161 EventDispatchThread.run() line: 122 Thread [SciJava-4b2922f6-Thread-27] (Suspended) Object.wait(long) line: not available [native method] EventQueue$1AWTInvocationLock(Object).wait() line: 485 Waiting for AWT event thread to read invocation request.
