Build 3.1 20050126 After upgrading to 20050125, I am quite often seeing hangs during debug process (after hitting a breakpoint, some step action causes a freeze). There doesn't seem to be a specific pattern. Usually terminating/restarting would work. org.eclipse.jdi.TimeoutException: Timeout occurred while waiting for packet 104515 at org.eclipse.jdi.internal.connect.PacketReceiveManager.getReply(PacketReceiveManager.java:160) at org.eclipse.jdi.internal.connect.PacketReceiveManager.getReply(PacketReceiveManager.java:169) at org.eclipse.jdi.internal.MirrorImpl.requestVM(MirrorImpl.java:174) at org.eclipse.jdi.internal.MirrorImpl.requestVM(MirrorImpl.java:192) at org.eclipse.jdi.internal.ThreadReferenceImpl.frames(ThreadReferenceImpl.java:187) at org.eclipse.jdi.internal.ThreadReferenceImpl.frame(ThreadReferenceImpl.java:140) at org.eclipse.jdt.internal.debug.core.model.JDIThread.getUnderlyingFrame(JDIThread.java:575) at org.eclipse.jdt.internal.debug.core.model.JDIStackFrame.getUnderlyingStackFrame(JDIStackFrame.java: 1000) at org.eclipse.jdt.internal.debug.core.model.JDIStackFrame.getUnderlyingMethod(JDIStackFrame.java:228) at org.eclipse.jdt.internal.debug.core.model.JDIStackFrame.isNative(JDIStackFrame.java:793) at org.eclipse.jdt.internal.debug.core.model.JDIStackFrame.supportsDropToFrame(JDIStackFrame.java:584) at org.eclipse.jdt.internal.debug.ui.actions.DropToFrameButton.selectionChanged(DropToFrameButton.jav a:62) at org.eclipse.ui.internal.PluginAction.refreshEnablement(PluginAction.java:195) at org.eclipse.ui.internal.PluginAction.selectionChanged(PluginAction.java:267) at org.eclipse.ui.internal.PluginAction.selectionChanged(PluginAction.java:278) at org.eclipse.jface.viewers.Viewer$2.run(Viewer.java:163) at org.eclipse.core.internal.runtime.InternalPlatform.run(InternalPlatform.java:1051) at org.eclipse.core.runtime.Platform.run(Platform.java:747) at org.eclipse.jface.viewers.Viewer.fireSelectionChanged(Viewer.java:161) at org.eclipse.jface.viewers.StructuredViewer.updateSelection(StructuredViewer.java:1676) at org.eclipse.jface.viewers.StructuredViewer.setSelection(StructuredViewer.java:1358) at org.eclipse.debug.internal.ui.views.RemoteTreeViewer.deferSelection(RemoteTreeViewer.java:305) at org.eclipse.debug.internal.ui.views.launch.LaunchViewEventHandler.doHandleSuspendThreadEvent(Laun chViewEventHandler.java:237) at org.eclipse.debug.internal.ui.views.launch.LaunchViewEventHandler.doHandleSuspendEvent(LaunchView EventHandler.java:204) at org.eclipse.debug.internal.ui.views.launch.LaunchViewEventHandler.doHandleDebugEvents(LaunchView EventHandler.java:123) at org.eclipse.debug.internal.ui.views.AbstractDebugEventHandler$EventProcessingJob.runInUIThread(Abst ractDebugEventHandler.java:103) at org.eclipse.ui.progress.UIJob$1.run(UIJob.java:96) at org.eclipse.swt.widgets.RunnableLock.run(RunnableLock.java:35) at org.eclipse.swt.widgets.Synchronizer.runAsyncMessages(Synchronizer.java:118) at org.eclipse.swt.widgets.Display.runAsyncMessages(Display.java:2854) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:2518) at org.eclipse.ui.internal.Workbench.runEventLoop(Workbench.java:1584) at org.eclipse.ui.internal.Workbench.runUI(Workbench.java:1550) at org.eclipse.ui.internal.Workbench.createAndRunWorkbench(Workbench.java:288) at org.eclipse.ui.PlatformUI.createAndRunWorkbench(PlatformUI.java:144) at org.eclipse.ui.internal.ide.IDEApplication.run(IDEApplication.java:102) at org.eclipse.core.internal.runtime.PlatformActivator$1.run(PlatformActivator.java:225) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:274) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:129) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:324) at org.eclipse.core.launcher.Main.basicRun(Main.java:255) at org.eclipse.core.launcher.Main.run(Main.java:811) at org.eclipse.core.launcher.Main.main(Main.java:795)
ignore beginning of description. I copied too much from bug 83937. Intention is too address communication with target in UI thread with this PR. Fixed in DropToFrameButton
please verify
The enablement is now in the background, but the action itself still runs in the main thread, and should submit a background job.
fixed
Verified.
This problem is back now that drop to frame has been migrated to the platform.
Fixed in DropToFrameActionDelegate. The enablement is now getting updated in a Job. The action execution was already being run in a job, no change to that code necessary.
Darin, please verify
