Proposed fix
Fix released for 3.4M4 The fix is trivial. Without it, there is a risk of ConcurrentModificationException at startup which can prevent the reconciler from running. Please approve for 3.3.2. (In reply to comment #2) > Fix released for 3.4M4 Thanks! +1 for 3.3.2 Fix released for 3.3.2 Verified for 3.4 M4 using build I20071211-0010 |
Created attachment 84323 [details] Eclipse .log file, from start of session through failures Build ID: M20070921-1145 I have a large workspace (521 projects, mostly plug-in projects, some features, some misc other projects). Auto-build is disabled (have never built in this workspace, just use it for reading code). Started eclipse today, and minimized. After a while noticed an error dialog, and found the attached errors, which show concurrent hash map access by the main thread and the reconciler thread. Both stack traces look similar to this (near the point of failure): !ENTRY org.eclipse.ui.workbench 4 2 2007-12-03 09:52:40.488 !MESSAGE Problems occurred when invoking code from plug-in: "org.eclipse.ui.workbench". !STACK 0 java.util.ConcurrentModificationException: concurrent access to HashMap attempted by Thread[main,6,main] at java.util.HashMap.onEntry(HashMap.java:213) at java.util.HashMap.transfer(HashMap.java:632) at java.util.HashMap.resize(HashMap.java:622) at java.util.HashMap.addEntry(HashMap.java:994) at java.util.HashMap.put(HashMap.java:510) at org.eclipse.jdt.internal.core.util.Util.getSourceAttachmentProperty(Util.java:1093) at org.eclipse.jdt.internal.core.DeltaProcessingState.initializeRoots(DeltaProcessingState.java:240) at org.eclipse.jdt.internal.core.JavaModelOperation.run(JavaModelOperation.java:717) at org.eclipse.core.internal.resources.Workspace.run(Workspace.java:1797) at org.eclipse.jdt.internal.core.JavaModelOperation.runOperation(JavaModelOperation.java:785) at org.eclipse.jdt.core.JavaCore.setClasspathContainer(JavaCore.java:4519) at org.eclipse.jdt.internal.launching.JREContainerInitializer.initialize(JREContainerInitializer.java:69) at org.eclipse.jdt.internal.core.JavaModelManager.initializeContainer(JavaModelManager.java:2218) at org.eclipse.jdt.internal.core.JavaModelManager.getClasspathContainer(JavaModelManager.java:1546) at org.eclipse.jdt.core.JavaCore.getClasspathContainer(JavaCore.java:1571) I'll attach a file with the relevant portion of the log (today's session).
