Here is a typical call stack captured while the UI thread was unresponsive: "main" prio=10 tid=0x0a016400 nid=0x355c runnable [0xff8bd000] java.lang.Thread.State: RUNNABLE at (C/C++) __kernel_vsyscall( ()) at (C/C++) Monitor::ILock(Thread*)( (/usr/local/buildtools/java/jdk6-google-v3/bin/../jre/lib/i386/client/libjvm.so)) at (C/C++) Monitor::lock_without_safepoint_check(Thread*)( (/usr/local/buildtools/java/jdk6-google-v3/bin/../jre/lib/i386/client/libjvm.so)) at (C/C++) Monitor::lock_without_safepoint_check()( (/usr/local/buildtools/java/jdk6-google-v3/bin/../jre/lib/i386/client/libjvm.so)) at (C/C++) SafepointSynchronize::block(JavaThread*)( (/usr/local/buildtools/java/jdk6-google-v3/bin/../jre/lib/i386/client/libjvm.so)) at (C/C++) JVM_InternString( (/usr/local/buildtools/java/jdk6-google-v3/bin/../jre/lib/i386/client/libjvm.so)) at (C/C++) Java_java_lang_String_intern( (/usr/local/buildtools/java/jdk6-google-v3/jre/lib/i386/libjava.so)) at java.lang.String.intern(Native Method) at org.eclipse.core.internal.resources.MarkerAttributeMap.get(MarkerAttributeMap.java:133) at org.eclipse.core.internal.resources.MarkerInfo.getAttribute(MarkerInfo.java:107) at org.eclipse.core.internal.resources.Marker.getAttribute(Marker.java:109) at org.eclipse.cdt.internal.ui.viewsupport.ProblemsLabelDecorator.isMarkerInRange(ProblemsLabelDecorator.java:222) at org.eclipse.cdt.internal.ui.viewsupport.ProblemsLabelDecorator.getErrorTicksFromMarkers(ProblemsLabelDecorator.java:207) at org.eclipse.cdt.internal.ui.viewsupport.ProblemsLabelDecorator.computeAdornmentFlags(ProblemsLabelDecorator.java:175) at org.eclipse.cdt.internal.ui.viewsupport.ProblemsLabelDecorator.decorateImage(ProblemsLabelDecorator.java:144) at org.eclipse.cdt.internal.ui.viewsupport.CUILabelProvider.decorateImage(CUILabelProvider.java:133) at org.eclipse.cdt.internal.ui.viewsupport.CUILabelProvider.getImage(CUILabelProvider.java:149) at org.eclipse.jface.viewers.DelegatingStyledCellLabelProvider.getImage(DelegatingStyledCellLabelProvider.java:184) at org.eclipse.jface.viewers.DecoratingStyledCellLabelProvider.getImage(DecoratingStyledCellLabelProvider.java:167) at org.eclipse.cdt.internal.ui.util.ResourceToItemsMapper.updateItem(ResourceToItemsMapper.java:91) at org.eclipse.cdt.internal.ui.util.ResourceToItemsMapper.resourceChanged(ResourceToItemsMapper.java:65) at org.eclipse.cdt.internal.ui.util.ProblemTreeViewer.handleLabelProviderChanged(ProblemTreeViewer.java:116) at org.eclipse.jface.viewers.ContentViewer$1.labelProviderChanged(ContentViewer.java:97) at org.eclipse.cdt.internal.ui.viewsupport.ProblemsLabelDecorator.fireProblemsChanged(ProblemsLabelDecorator.java:351) at org.eclipse.cdt.internal.ui.viewsupport.ProblemsLabelDecorator$1.problemsChanged(ProblemsLabelDecorator.java:326) at org.eclipse.cdt.internal.ui.util.ProblemMarkerManager$1.run(ProblemMarkerManager.java:183) at org.eclipse.swt.widgets.RunnableLock.run(RunnableLock.java:35) at org.eclipse.swt.widgets.Synchronizer.runAsyncMessages(Synchronizer.java:134) - locked <0x907dfc30> (a org.eclipse.swt.widgets.RunnableLock) at org.eclipse.swt.widgets.Display.runAsyncMessages(Display.java:3515) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:3164) at org.eclipse.ui.internal.Workbench.runEventLoop(Workbench.java:2644) at org.eclipse.ui.internal.Workbench.runUI(Workbench.java:2606) at org.eclipse.ui.internal.Workbench.access$4(Workbench.java:2440) at org.eclipse.ui.internal.Workbench$7.run(Workbench.java:683) at org.eclipse.core.databinding.observable.Realm.runWithDefault(Realm.java:332) at org.eclipse.ui.internal.Workbench.createAndRunWorkbench(Workbench.java:676) at org.eclipse.ui.PlatformUI.createAndRunWorkbench(PlatformUI.java:149) at org.eclipse.ui.internal.ide.application.IDEApplication.start(IDEApplication.java:115) at org.eclipse.equinox.internal.app.EclipseAppHandle.run(EclipseAppHandle.java:196) at org.eclipse.core.runtime.internal.adaptor.EclipseAppLauncher.runApplication(EclipseAppLauncher.java:110) at org.eclipse.core.runtime.internal.adaptor.EclipseAppLauncher.start(EclipseAppLauncher.java:79) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:369) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:179) at (C/C++) _fini(Unknown Source) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:616) at org.eclipse.equinox.launcher.Main.invokeFramework(Main.java:619) at org.eclipse.equinox.launcher.Main.basicRun(Main.java:574) at org.eclipse.equinox.launcher.Main.run(Main.java:1407)
ProblemTreeViewer indicates C/C++ Projects view. Does the same happen with the Project Explorer?
(In reply to comment #1) > ProblemTreeViewer indicates C/C++ Projects view. Does the same happen with > the Project Explorer? I just confirmed that this also happens with the PE. JDT has has some optimizations in place, esp. breaking the loop in getErrorTicksFromMarkers() as soon as the problem severity reaches ERROR (it can't get higher).
(In reply to comment #2) > JDT has has some optimizations in place, esp. breaking the loop in > getErrorTicksFromMarkers() as soon as the problem severity reaches ERROR (it > can't get higher). Sorry, red herring. That optimization is already in place.
In fact, the view in question is probably the Outline view.

Is this still an issue?
(In reply to Nathan Ridge from comment #6) > Is this still an issue? I don't know. I haven't noticed those stacks lately, but likely because I didn't pay attention.
