I20110729-0200 (4.2) I had the focus in the Quick Access field and then switched to another application. When I came back to Eclipse, I got an error dialog with this exception: org.eclipse.swt.SWTException: Failed to execute runnable (org.eclipse.e4.core.di.InjectionException: java.lang.NullPointerException) at org.eclipse.swt.SWT.error(SWT.java:4283) at org.eclipse.swt.SWT.error(SWT.java:4198) at org.eclipse.swt.widgets.Synchronizer.runAsyncMessages(Synchronizer.java:138) at org.eclipse.swt.widgets.Display.runAsyncMessages(Display.java:3935) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:3612) at org.eclipse.e4.ui.internal.workbench.swt.PartRenderingEngine$9.run(PartRenderingEngine.java:969) at org.eclipse.core.databinding.observable.Realm.runWithDefault(Realm.java:332) at org.eclipse.e4.ui.internal.workbench.swt.PartRenderingEngine.run(PartRenderingEngine.java:885) at org.eclipse.e4.ui.internal.workbench.E4Workbench.createAndRunUI(E4Workbench.java:90) at org.eclipse.ui.internal.Workbench$3.run(Workbench.java:539) at org.eclipse.core.databinding.observable.Realm.runWithDefault(Realm.java:332) at org.eclipse.ui.internal.Workbench.createAndRunWorkbench(Workbench.java:519) at org.eclipse.ui.PlatformUI.createAndRunWorkbench(PlatformUI.java:149) at org.eclipse.ui.internal.ide.application.IDEApplication.start(IDEApplication.java:123) at org.eclipse.equinox.internal.app.EclipseAppHandle.run(EclipseAppHandle.java:196) 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:344) 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:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.eclipse.equinox.launcher.Main.invokeFramework(Main.java:622) at org.eclipse.equinox.launcher.Main.basicRun(Main.java:577) at org.eclipse.equinox.launcher.Main.run(Main.java:1410) Caused by: org.eclipse.e4.core.di.InjectionException: java.lang.NullPointerException at org.eclipse.e4.core.internal.di.MethodRequestor.execute(MethodRequestor.java:63) at org.eclipse.e4.core.internal.di.InjectorImpl.invokeUsingClass(InjectorImpl.java:228) at org.eclipse.e4.core.internal.di.InjectorImpl.invokeUsingClass(InjectorImpl.java:234) at org.eclipse.e4.core.internal.di.InjectorImpl.invoke(InjectorImpl.java:209) at org.eclipse.e4.core.contexts.ContextInjectionFactory.invoke(ContextInjectionFactory.java:123) at org.eclipse.e4.core.commands.internal.HandlerServiceImpl.canExecute(HandlerServiceImpl.java:99) at org.eclipse.e4.ui.workbench.renderers.swt.MenuManagerRendererFilter.updateElementVisibility(MenuManagerRendererFilter.java:344) at org.eclipse.e4.ui.workbench.renderers.swt.MenuManagerRendererFilter.updateElementVisibility(MenuManagerRendererFilter.java:326) at org.eclipse.ui.internal.WorkbenchWindow$6.run(WorkbenchWindow.java:546) at org.eclipse.swt.widgets.RunnableLock.run(RunnableLock.java:35) at org.eclipse.swt.widgets.Synchronizer.runAsyncMessages(Synchronizer.java:135) ... 23 more Caused by: java.lang.NullPointerException at org.eclipse.e4.ui.workbench.renderers.swt.cocoa.AbstractWindowHandler.canExecute(AbstractWindowHandler.java:32) at sun.reflect.GeneratedMethodAccessor16.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.eclipse.e4.core.internal.di.MethodRequestor.execute(MethodRequestor.java:56) ... 33 more
The code in question is: if (shell == null) { return false; } NSWindow window = shell.view.window(); // NPE I can't reproduce this locally, but I guess 'shell.view' must be null. I'll put in a check, and a corresponding check in org.eclipse.ui.cocoa's AbstractWindowHandler too.
Committed fixes to the R4_development and R3_development branches. I hope I got this right.
