I am using I20030917 with the Sun SDK 1.4.2_02. I was editing a new Java file - see below - and I got a popup saying that an error had occurred and I should check the Eclipse log. The error occurred while I was trying to type the word ArrayList. /* * Created on Nov 3, 2003 * * To change this generated comment go to * Window>Preferences>Java>Code Generation>Code and Comments */ package com.cryptocard.cryptoadmin.consolecli; /** * @author jonathan * * To change this generated comment go to * Window>Preferences>Java>Code Generation>Code and Comments */ public class CliSource extends CliCommandSource { /** * */ public CliSource(Array) <<<========= Error happened here { super(); // TODO Auto-generated constructor stub } } The stack dump from the Eclipse log follows !ENTRY org.eclipse.ui.workbench 4 2 Nov 03, 2003 14:37:08.559 !MESSAGE Problems occurred when invoking code from plug- in: "org.eclipse.ui.workbench". !STACK 0 java.lang.ArrayIndexOutOfBoundsException: 1 at org.eclipse.jdt.internal.compiler.parser.diagnose.Util.isInInterval (Util.java:165) at org.eclipse.jdt.internal.compiler.parser.diagnose.LexStream.readTokenFromScanne r(LexStream.java:81) at org.eclipse.jdt.internal.compiler.parser.diagnose.LexStream.token (LexStream.java:137) at org.eclipse.jdt.internal.compiler.parser.diagnose.LexStream.kind (LexStream.java:177) at org.eclipse.jdt.internal.compiler.parser.diagnose.DiagnoseParser.diagnoseParse (DiagnoseParser.java:288) at org.eclipse.jdt.internal.compiler.parser.Parser.reportSyntaxErrors (Parser.java:5654) at org.eclipse.jdt.internal.compiler.parser.Parser.parse (Parser.java:5633) at org.eclipse.jdt.internal.compiler.parser.Parser.parse (Parser.java:5944) at org.eclipse.jdt.internal.compiler.parser.Parser.parse (Parser.java:5916) at org.eclipse.jdt.internal.compiler.SourceElementParser.parseCompilationUnit (SourceElementParser.java:1041) at org.eclipse.jdt.internal.core.CompilationUnit.buildStructure (CompilationUnit.java:121) at org.eclipse.jdt.internal.core.Openable.generateInfos (Openable.java:200) at org.eclipse.jdt.internal.core.JavaElement.openWhenClosed (JavaElement.java:487) at org.eclipse.jdt.internal.core.CompilationUnit.makeConsistent (CompilationUnit.java:918) at org.eclipse.jdt.internal.core.ReconcileWorkingCopyOperation.executeOperation (ReconcileWorkingCopyOperation.java:48) at org.eclipse.jdt.internal.core.JavaModelOperation.execute (JavaModelOperation.java:366) at org.eclipse.jdt.internal.core.JavaModelOperation.run (JavaModelOperation.java:705) at org.eclipse.jdt.internal.core.JavaElement.runOperation (JavaElement.java:523) at org.eclipse.jdt.internal.core.CompilationUnit.reconcile (CompilationUnit.java:1031) at org.eclipse.jdt.internal.core.CompilationUnit.reconcile (CompilationUnit.java:1007) at org.eclipse.jdt.internal.core.CompilationUnit.reconcile (CompilationUnit.java:1000) at org.eclipse.jdt.internal.ui.browsing.JavaBrowsingPart.getElementForInputAt (JavaBrowsingPart.java:1295) at org.eclipse.jdt.internal.ui.browsing.JavaBrowsingPart.setSelectionFromEditor (JavaBrowsingPart.java:1146) at org.eclipse.jdt.internal.ui.browsing.JavaBrowsingPart.selectionChanged (JavaBrowsingPart.java:698) at org.eclipse.jdt.internal.ui.browsing.TypesView.selectionChanged (TypesView.java:200) at org.eclipse.ui.internal.AbstractSelectionService$4.run (AbstractSelectionService.java:178) at org.eclipse.core.internal.runtime.InternalPlatform.run (InternalPlatform.java:1016) at org.eclipse.core.runtime.Platform.run(Platform.java:420) at org.eclipse.ui.internal.AbstractSelectionService.firePostSelection (AbstractSelectionService.java:176) at org.eclipse.ui.internal.AbstractSelectionService$2.selectionChanged (AbstractSelectionService.java:76) at org.eclipse.jface.text.TextViewer.firePostSelectionChanged (TextViewer.java:2099) at org.eclipse.jface.text.TextViewer.firePostSelectionChanged (TextViewer.java:2052) at org.eclipse.jface.text.TextViewer$4.run(TextViewer.java:2031) at org.eclipse.swt.widgets.Display.runTimer(Display.java:2229) at org.eclipse.swt.widgets.Display.messageProc(Display.java:1763) at org.eclipse.swt.internal.win32.OS.DispatchMessageW(Native Method) at org.eclipse.swt.internal.win32.OS.DispatchMessage(OS.java:1343) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:1875) at org.eclipse.ui.internal.Workbench.runEventLoop(Workbench.java:2037) at org.eclipse.ui.internal.Workbench.run(Workbench.java:2020) at org.eclipse.core.internal.boot.InternalBootLoader.run (InternalBootLoader.java:858) at org.eclipse.core.boot.BootLoader.run(BootLoader.java:461) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke (NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke (DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:324) at org.eclipse.core.launcher.Main.basicRun(Main.java:295) at org.eclipse.core.launcher.Main.run(Main.java:751) at org.eclipse.core.launcher.Main.main(Main.java:587)
I can not reproduce the problem. Jonathan - Can you reproduce the bug with this simple test case every time?
Unfortunately, no. I get anywhere between 10 and 20 of these a day and they all exhibit different stack traces. I run on a dual 933Mhz machine with 1GB of physical memory at work. I also experience the problem at home but less frequently. There I run on a dual Athlon MP2200 system with 2GB of memory. I believe that all these problems are related to thread synchronization issues between the code that is parsing the statement being typed and the code that is managing the GUI. Reproducing the problem is difficult because I believe that you need an exact sequence of timing to make any specific set of symptoms reappear. I believe that you may need to do a code audit to verify that there are no synchronization holes and plug those which may exist. Regards Jonathan
The method org.eclipse.jdt.internal.compiler.parser.diagnose.Util#computeDietRange (TypeDeclaration[] types) use static fields. I think the problem come from these fields and multithreading. I change computeDietRange() to not use static fields. Fixed.
