I found this at the top of my log this morning. Not sure what caused it: eclipse.buildId=I20090129-0100 java.fullversion=J2RE 1.5.0 IBM J9 2.3 Windows XP x86-32 j9vmwi3223-20070201 (JIT enabled) J9VM - 20070131_11312_lHdSMR JIT - 20070109_1805ifx1_r8 GC - 200701_09 BootLoader constants: OS=win32, ARCH=x86, WS=win32, NL=en_US Framework arguments: file:/C:/sdk3.5/eclipse/plugins/org.eclipse.equinox.launcher_1.0.200.v20081201-1815.jar Command-line arguments: -os win32 -ws win32 -arch x86 file:/C:/sdk3.5/eclipse/plugins/org.eclipse.equinox.launcher_1.0.200.v20081201-1815.jar org.eclipse.swt.SWTException: Failed to execute runnable (java.lang.IllegalArgumentException: input or wait flag are null) at org.eclipse.swt.SWT.error(SWT.java:3860) at org.eclipse.swt.SWT.error(SWT.java:3775) at org.eclipse.swt.widgets.Synchronizer.runAsyncMessages(Synchronizer.java:136) at org.eclipse.swt.widgets.Display.runAsyncMessages(Display.java:3852) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:3473) at org.eclipse.ui.internal.Workbench.runEventLoop(Workbench.java:2388) at org.eclipse.ui.internal.Workbench.runUI(Workbench.java:2352) at org.eclipse.ui.internal.Workbench.access$4(Workbench.java:2204) at org.eclipse.ui.internal.Workbench$5.run(Workbench.java:499) at org.eclipse.core.databinding.observable.Realm.runWithDefault(Realm.java:333) at org.eclipse.ui.internal.Workbench.createAndRunWorkbench(Workbench.java:492) at org.eclipse.ui.PlatformUI.createAndRunWorkbench(PlatformUI.java:149) at org.eclipse.ui.internal.ide.application.IDEApplication.start(IDEApplication.java:113) at org.eclipse.equinox.internal.app.EclipseAppHandle.run(EclipseAppHandle.java:194) at org.eclipse.core.runtime.internal.adaptor.EclipseAppLauncher.runApplication(EclipseAppLauncher.java:110) at org.eclipse.core.runtime.internal.adaptor.EclipseAppLauncher.start(EclipseAppLauncher.java:79) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:368) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:179) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:64) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:615) at org.eclipse.equinox.launcher.Main.invokeFramework(Main.java:550) at org.eclipse.equinox.launcher.Main.basicRun(Main.java:505) at org.eclipse.equinox.launcher.Main.run(Main.java:1264) at org.eclipse.equinox.launcher.Main.main(Main.java:1240) Caused by: java.lang.IllegalArgumentException: input or wait flag are null at org.eclipse.jdt.internal.ui.javaeditor.ASTProvider.getAST(ASTProvider.java:412) at org.eclipse.jdt.ui.SharedASTProvider.getAST(SharedASTProvider.java:126) at org.eclipse.jdt.internal.ui.text.correction.AssistContext.getASTRoot(AssistContext.java:84) at org.eclipse.jdt.internal.ui.text.java.hover.ProblemHover$ProblemInfo.getJavaAnnotationFixes(ProblemHover.java:212) at org.eclipse.jdt.internal.ui.text.java.hover.ProblemHover$ProblemInfo.getCompletionProposals(ProblemHover.java:192) at org.eclipse.jdt.internal.ui.text.java.hover.AbstractAnnotationHover$AnnotationInformationControl.deferredCreateContent(AbstractAnnotationHover.java:275) at org.eclipse.jdt.internal.ui.text.java.hover.AbstractAnnotationHover$AnnotationInformationControl.setInput(AbstractAnnotationHover.java:181) at org.eclipse.jface.text.AbstractInformationControlManager.internalShowInformationControl(AbstractInformationControlManager.java:1170) at org.eclipse.jface.text.AbstractInformationControlManager.presentInformation(AbstractInformationControlManager.java:1139) at org.eclipse.jface.text.AbstractHoverInformationControlManager.presentInformation(AbstractHoverInformationControlManager.java:902) at org.eclipse.jface.text.TextViewerHoverManager.doPresentInformation(TextViewerHoverManager.java:243) at org.eclipse.jface.text.TextViewerHoverManager$5.run(TextViewerHoverManager.java:233) at org.eclipse.swt.widgets.RunnableLock.run(RunnableLock.java:35) at org.eclipse.swt.widgets.Synchronizer.runAsyncMessages(Synchronizer.java:133) ... 23 more
Darin, this should not happen (obviously). We cannot do much without further steps.
I20090714-0800 I got the same exception in my log this morning while editing the class CommonTab in org.eclipse.debug.ui. I added the following code and hit Ctrl+S and saw the exception. IResource resource = (IResource) dialog.getFirstResult(); if(resource != null) { String arg = resource.getFullPath().toString(); String fileLoc = VariablesPlugin .getDefault() .getStringVariableManager() .generateVariableExpression("workspace_loc", arg); fFileText.setText(fileLoc); } I did not use content assist if that helps in any way.
Michael, can you reproduce with your steps (I can't).

*** Bug 295392 has been marked as a duplicate of this bug. ***
Steps to reproduce in I20091208-0100: - new workspace - paste: package p; public class C { public static void main(String[] args) { System.out.println(2); } } - on Annotations preference page, configure Breakpoints to Show in Text as Vertical Bar - Open Declaration of println method - set a breakpoint in println method - hover over the line with the breakpoint Regardless of the solution for this bug, I think the main constructor of AssistContext should contain: Assert.isNotNull(cu); Assert.isNotNull(waitFlag);
Fixed in HEAD. Available in builds >= I20091215-0800.
