Bug 67187 [implementation] Concurrent modification of CompilationUnitDocumentProvider's ReverseMap
Was just scrolling through a Java file and got a popup with the following info: Java AST creation (Error: An internal error occurred during: "Java AST creation".) An internal error occurred during: "Java AST creation". java.lang.IndexOutOfBoundsException: Index: 62, Size: 60 java.util.ArrayList.RangeCheck(ArrayList.java:507) java.util.ArrayList.get(ArrayList.java:324) org.eclipse.jdt.internal.ui.javaeditor.CompilationUnitDocumentProvider$ReverseM ap.get(CompilationUnitDocumentProvider.java:325) org.eclipse.jdt.internal.ui.javaeditor.CompilationUnitDocumentProvider$Compilat ionUnitAnnotationModel.addAnnotation(CompilationUnitDocumentProvider.java:665) org.eclipse.jface.text.source.AnnotationModel.addAnnotation (AnnotationModel.java:163) org.eclipse.jdt.internal.ui.text.correction.QuickAssistLightBulbUpdater.calcula teLightBulb(QuickAssistLightBulbUpdater.java:233) org.eclipse.jdt.internal.ui.text.correction.QuickAssistLightBulbUpdater.doSelec tionChanged(QuickAssistLightBulbUpdater.java:221) org.eclipse.jdt.internal.ui.text.correction.QuickAssistLightBulbUpdater.access$ 0(QuickAssistLightBulbUpdater.java:204) org.eclipse.jdt.internal.ui.text.correction.QuickAssistLightBulbUpdater$1.selec tionChanged(QuickAssistLightBulbUpdater.java:128) org.eclipse.jdt.internal.ui.viewsupport.SelectionListenerWithASTManager$PartLis tenerGroup.calculateASTandInform(SelectionListenerWithASTManager.java:164) org.eclipse.jdt.internal.ui.viewsupport.SelectionListenerWithASTManager$3.run (SelectionListenerWithASTManager.java:136) org.eclipse.core.internal.jobs.Worker.run(Worker.java:66) Wasn't doing anything remarkable at the time - certainly nothing that I would expect would induce this...
