I noticed that code assist stopped working in my compilation unit I was editing, and then found this in the log: !ENTRY org.eclipse.ui 4 4 Oct 10, 2002 09:56:05.316 !MESSAGE Unhandled exception caught in event loop. !ENTRY org.eclipse.ui 4 0 Oct 10, 2002 09:56:05.326 !MESSAGE java.lang.NullPointerException !STACK 0 java.lang.NullPointerException at org.eclipse.jdt.core.dom.MethodBinding.getKey(MethodBinding.java:145) at org.eclipse.jdt.core.dom.DefaultBindingResolver.resolveMethod (DefaultBindingResolver.java:396) at org.eclipse.jdt.core.dom.MethodDeclaration.resolveBinding (MethodDeclaration.java:441) at org.eclipse.jdt.core.dom.ASTConverter.convert(ASTConverter.java:722) at org.eclipse.jdt.core.dom.ASTConverter.buildBodyDeclarations (ASTConverter.java:230) at org.eclipse.jdt.core.dom.ASTConverter.convert(ASTConverter.java:169) at org.eclipse.jdt.core.dom.ASTConverter.convert(ASTConverter.java:69) at org.eclipse.jdt.core.dom.AST.parseCompilationUnit(AST.java:241) at org.eclipse.jdt.internal.corext.codemanipulation.OrganizeImportsOperation.findTy peReferences(OrganizeImportsOperation.java:569) at org.eclipse.jdt.internal.corext.codemanipulation.OrganizeImportsOperation.run (OrganizeImportsOperation.java:516) at org.eclipse.jdt.internal.core.BatchOperation.executeOperation (BatchOperation.java:34) at org.eclipse.jdt.internal.core.JavaModelOperation.execute (JavaModelOperation.java:320) at org.eclipse.jdt.internal.core.JavaModelOperation.run (JavaModelOperation.java:620) at org.eclipse.core.internal.resources.Workspace.run (Workspace.java:1378) at org.eclipse.jdt.core.JavaCore.run(JavaCore.java:2154) at org.eclipse.jdt.internal.ui.actions.WorkbenchRunnableAdapter.run (WorkbenchRunnableAdapter.java:34) at org.eclipse.jdt.internal.ui.util.BusyIndicatorRunnableContext$BusyRunnable.inter nalRun(BusyIndicatorRunnableContext.java:107) at org.eclipse.jdt.internal.ui.util.BusyIndicatorRunnableContext$BusyRunnable.run (BusyIndicatorRunnableContext.java:74) at org.eclipse.swt.custom.BusyIndicator.showWhile(BusyIndicator.java (Compiled Code)) at org.eclipse.jdt.internal.ui.util.BusyIndicatorRunnableContext.run (BusyIndicatorRunnableContext.java:120) at org.eclipse.jdt.ui.actions.OrganizeImportsAction.runOnSingle (OrganizeImportsAction.java:360) at org.eclipse.jdt.ui.actions.OrganizeImportsAction.run (OrganizeImportsAction.java:243) at org.eclipse.jdt.ui.actions.SelectionDispatchAction.dispatchRun (SelectionDispatchAction.java:193) at org.eclipse.jdt.ui.actions.SelectionDispatchAction.run (SelectionDispatchAction.java:169) at org.eclipse.jface.action.Action.runWithEvent(Action.java:749) at org.eclipse.ui.internal.registry.AcceleratorScope$AcceleratorAction.run (AcceleratorScope.java:289) at org.eclipse.ui.internal.registry.AcceleratorScope.processKey (AcceleratorScope.java:249) at org.eclipse.ui.internal.KeyBindingMenu$3.handleEvent (KeyBindingMenu.java:90) at org.eclipse.swt.widgets.Display.runDeferredEvents(Display.java (Compiled Code)) at org.eclipse.swt.widgets.Display.runDeferredEvents(Display.java (Compiled Code)) at org.eclipse.swt.widgets.Display.runDeferredEvents(Display.java (Compiled Code)) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java (Compiled Code)) at org.eclipse.ui.internal.Workbench.runEventLoop(Workbench.java (Compiled Code)) at org.eclipse.ui.internal.Workbench.run(Workbench.java:1321) at org.eclipse.core.internal.boot.InternalBootLoader.run (InternalBootLoader.java:775) at org.eclipse.core.boot.BootLoader.run(BootLoader.java:462) at java.lang.reflect.Method.invoke(Native Method) at org.eclipse.core.launcher.Main.basicRun(Main.java:247) at org.eclipse.core.launcher.Main.run(Main.java:703) at org.eclipse.core.launcher.Main.main(Main.java:539)
Could not reproduce after restarting the workspace.
I will investigate.
I added a new check. It seems possible in some cases that the return type is null. This is the case in code assist. Fixed and released in 2.1 stream.
Change milestone.
Verified.
