Build ID: I20080516-1333 Possibly related to bug 237166. With a large number of projects in the workspace. I replaced a java file with the latest version from CVS and when the auto build kicked in my workspace became full of errors and the exception below constantly added to the error log. This leaves many, if not all, of the projects in the workspace with build errors and is difficult to recover from. java.lang.ArrayIndexOutOfBoundsException at java.util.Arrays.mergeSort(Unknown Source) at java.util.Arrays.sort(Unknown Source) at java.util.Arrays.sort(Unknown Source) at org.eclipse.core.internal.content.ContentTypeCatalog.internalFindContentTypesFor(ContentTypeCatalog.java:446) at org.eclipse.core.internal.content.ContentTypeCatalog.internalFindContentTypesFor(ContentTypeCatalog.java:384) at org.eclipse.core.internal.content.ContentTypeCatalog.getDescriptionFor(ContentTypeCatalog.java:304) at org.eclipse.core.internal.content.ContentTypeCatalog.getDescriptionFor(ContentTypeCatalog.java:318) at org.eclipse.core.internal.content.ContentTypeMatcher.getDescriptionFor(ContentTypeMatcher.java:86) at org.eclipse.core.internal.resources.ContentDescriptionManager.readDescription(ContentDescriptionManager.java:400) at org.eclipse.core.internal.resources.ContentDescriptionManager.getDescriptionFor(ContentDescriptionManager.java:309) at org.eclipse.core.internal.resources.File.internalGetCharset(File.java:260) at org.eclipse.core.internal.resources.File.getCharset(File.java:221) at org.eclipse.core.internal.resources.File.getCharset(File.java:208) at org.eclipse.core.internal.filebuffers.ResourceTextFileBuffer.cacheEncodingState(ResourceTextFileBuffer.java:484) at org.eclipse.core.internal.filebuffers.ResourceTextFileBuffer.initializeFileBufferContent(ResourceTextFileBuffer.java:285) at org.eclipse.core.internal.filebuffers.ResourceFileBuffer.create(ResourceFileBuffer.java:241) at org.eclipse.core.internal.filebuffers.TextFileBufferManager.connect(TextFileBufferManager.java:112) at org.eclipse.pde.internal.core.builders.XMLErrorReporter.<init>(XMLErrorReporter.java:95) at org.eclipse.pde.internal.core.builders.FeatureErrorReporter.<init>(FeatureErrorReporter.java:41) at org.eclipse.pde.internal.core.builders.FeatureConsistencyChecker.checkFile(FeatureConsistencyChecker.java:98) at org.eclipse.pde.internal.core.builders.FeatureConsistencyChecker.access$1(FeatureConsistencyChecker.java:95) at org.eclipse.pde.internal.core.builders.FeatureConsistencyChecker$DeltaVisitor.visit(FeatureConsistencyChecker.java:58) at org.eclipse.core.internal.events.ResourceDelta.accept(ResourceDelta.java:68) at org.eclipse.core.internal.events.ResourceDelta.accept(ResourceDelta.java:79) at org.eclipse.core.internal.events.ResourceDelta.accept(ResourceDelta.java:48) at org.eclipse.pde.internal.core.builders.FeatureConsistencyChecker.build(FeatureConsistencyChecker.java:83) at org.eclipse.core.internal.events.BuildManager$2.run(BuildManager.java:633) at org.eclipse.core.runtime.SafeRunner.run(SafeRunner.java:37) at org.eclipse.core.internal.events.BuildManager.basicBuild(BuildManager.java:170) at org.eclipse.core.internal.events.BuildManager.basicBuild(BuildManager.java:201) at org.eclipse.core.internal.events.BuildManager$1.run(BuildManager.java:253) at org.eclipse.core.runtime.SafeRunner.run(SafeRunner.java:37) at org.eclipse.core.internal.events.BuildManager.basicBuild(BuildManager.java:256) at org.eclipse.core.internal.events.BuildManager.basicBuildLoop(BuildManager.java:309) at org.eclipse.core.internal.events.BuildManager.build(BuildManager.java:341) at org.eclipse.core.internal.events.AutoBuildJob.doBuild(AutoBuildJob.java:140) at org.eclipse.core.internal.events.AutoBuildJob.run(AutoBuildJob.java:238) at org.eclipse.core.internal.jobs.Worker.run(Worker.java:55)
Christian, Alex - this is the 4th different walkback that we've seen in the last 2 days that ends up with an AIOOBE at Arrays.mergeSort. Alex & I saw one yesterday from an SWT stack trace and we have 2 in the compiler (sorting fields & methods). This looks more and more like a VM bug, but I don't have proof yet. I suggest changing VMs to see if the problem is reproduceable on more than 1 VM (1.4, 1.5 vs. 6.0) & more than 1 vendor (sun vs. j9).
sending over to UI since it is their builder.
Moving to platform text for comment - we're just connecting a file to a buffer manager.
What VM are you using? My guess is a VM or JIT bug, but if not, it's definitely not a Text bug as we correctly call File.getCharset().
java version "1.5.0" Java(TM) 2 Runtime Environment, Standard Edition (build pwi32dev-20070511 (SR5)) IBM J9 VM (build 2.3, J2RE 1.5.0 IBM J9 2.3 Windows XP x86-32 j9vmwi3223-2007042 6 (JIT enabled) J9VM - 20070420_12448_lHdSMR JIT - 20070419_1806_r8 GC - 200704_19) JCL - 20070511
I've been getting similar errors with a sun 1.6 vm and (recent?) J9 1.6
Alex: similar errors in ContentTypeCatalog, or other users of mergeSort?
unknown. Merge sort errors when synching with CVS etc.
Have closed bug 237166 as NOT_ECLIPSE since the AIOOBEs are only appearing on certain VMs.
Sounds the same here. *** This bug has been marked as a duplicate of bug 237166 ***
