Build: 20020314 I was switching back and forth between Netscape and Eclipse, and suddenly Eclipse locked up. When I hit ctrl-break I get the following stack traces. NOTE: Eclipse is using 100% of my CPU. Full thread dump Java HotSpot(TM) Client VM (1.4.1-beta-b02 mixed mode): "org.eclipse.jface.text.reconciler.MonoReconciler" daemon prio=2 tid=0x0AB5FC88 nid=0x318 waiting on monitor [d15f000..d15fdb4] at java.lang.Object.wait(Native Method) - waiting on <03A19CD0> (a org.eclipse.jface.text.reconciler.DirtyRegion Queue) at org.eclipse.jface.text.reconciler.AbstractReconciler$BackgroundThread .run(AbstractReconciler.java:128) - locked <03A19CD0> (a org.eclipse.jface.text.reconciler.DirtyRegionQueu e) "Java indexing" daemon prio=5 tid=0x0ABBD608 nid=0x13c waiting on monitor [b94f0 00..b94fdb4] at java.lang.Thread.sleep(Native Method) at org.eclipse.jdt.internal.core.search.processing.JobManager.run(JobMan ager.java:276) at java.lang.Thread.run(Thread.java:536) "Signal Dispatcher" daemon prio=10 tid=0x0023FD68 nid=0x418 waiting on monitor [ 0..0] "Finalizer" daemon prio=9 tid=0x0AA90E08 nid=0x438 waiting on monitor [ad4f000.. ad4fdb4] at java.lang.Object.wait(Native Method) - waiting on <02EE2F28> (a java.lang.ref.ReferenceQueue$Lock) at java.lang.ref.ReferenceQueue.remove(ReferenceQueue.java:111) - locked <02EE2F28> (a java.lang.ref.ReferenceQueue$Lock) at java.lang.ref.ReferenceQueue.remove(ReferenceQueue.java:127) at java.lang.ref.Finalizer$FinalizerThread.run(Finalizer.java:159) "Reference Handler" daemon prio=10 tid=0x0AA90208 nid=0x484 waiting on monitor [ ad0f000..ad0fdb4] at java.lang.Object.wait(Native Method) - waiting on <02EE2F90> (a java.lang.ref.Reference$Lock) at java.lang.Object.wait(Object.java:426) at java.lang.ref.Reference$ReferenceHandler.run(Reference.java:113) - locked <02EE2F90> (a java.lang.ref.Reference$Lock) "main" prio=5 tid=0x00234700 nid=0x104 runnable [6f000..6fc3c] at org.eclipse.jdt.internal.core.OverflowingLRUCache.privateRemoveEntry( OverflowingLRUCache.java:284) at org.eclipse.jdt.internal.core.OverflowingLRUCache.makeSpace(Overflowi ngLRUCache.java:171) at org.eclipse.jdt.internal.core.OverflowingLRUCache.put(OverflowingLRUC ache.java:345) at org.eclipse.jdt.internal.core.BufferManager.addBuffer(BufferManager.j ava:38) at org.eclipse.jdt.internal.core.BufferManager.openBuffer(BufferManager. java:84) at org.eclipse.jdt.internal.core.ClassFile.openBuffer(ClassFile.java:364 ) at org.eclipse.jdt.internal.core.ClassFile.getBuffer(ClassFile.java:206) at org.eclipse.jdt.internal.corext.javadoc.JavaDocAccess.getJavaDoc(Java DocAccess.java:36) at org.eclipse.jdt.internal.ui.text.java.hover.JavaTypeHover.getHoverInf o(JavaTypeHover.java:120) at org.eclipse.jdt.internal.ui.text.java.hover.JavaTextHover.getHoverInf o(JavaTextHover.java:300) at org.eclipse.jface.text.TextViewerHoverManager.computeInformation(Text ViewerHoverManager.java:56) at org.eclipse.jface.text.AbstractInformationControlManager.showInformat ion(AbstractInformationControlManager.java:536) at org.eclipse.jface.text.AbstractHoverInformationControlManager$MouseTr acker.mouseHover(AbstractHoverInformationControlManager.java:233) at org.eclipse.swt.widgets.TypedListener.handleEvent(TypedListener.java: 207) at org.eclipse.swt.widgets.EventTable.sendEvent(EventTable.java:74) at org.eclipse.swt.widgets.Widget.notifyListeners(Widget.java:637) at org.eclipse.swt.widgets.Display.runDeferredEvents(Display.java:1420) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:1208) at org.eclipse.ui.internal.Workbench.runEventLoop(Workbench.java:692) at org.eclipse.ui.internal.Workbench.run(Workbench.java:675) at org.eclipse.core.internal.boot.InternalBootLoader.run(InternalBootLoa der.java:777) at org.eclipse.core.boot.BootLoader.run(BootLoader.java:319) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl. java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAcces sorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:324) at org.eclipse.core.launcher.Main.basicRun(Main.java:151) at org.eclipse.core.launcher.Main.run(Main.java:502) at org.eclipse.core.launcher.Main.main(Main.java:362) "VM Thread" prio=5 tid=0x0094F488 nid=0x490 runnable "VM Periodic Task Thread" prio=10 tid=0x0023F258 nid=0x468 waiting on monitor "Suspend Checker Thread" prio=10 tid=0x0023FBA8 nid=0x3e8 runnable
Your stack trace doesn't show any infinite loop. What makes you think there was one ?
Top 3 reasons I think Eclipse was in an infinite loop: 1. Every time I hit a Ctrl-Break I got a stack dump somewhere in the OverflowingLRUCache, but in different locations. 2. CPU @ 100% 3. Eclipse UI was completely locked
We think we have made appropriate changes in this area. Some buffers may not have been closed in the past. Closing this one, please let us know if you see similar symptoms with the next integration build. Fixed
