Created attachment 151716 [details] possible fix I20091103-0941 - press Alt+Shift+F2 - click a main toolbar button (e.g. 'Open Type' or 'Debug'). => Boom! Attaching a possible patch (though I have to admit that I don't have much experience writing code that catches Exception ;-). Error Mon Nov 09 18:11:41 CET 2009 Unhandled event loop exception java.lang.NullPointerException at org.eclipse.pde.internal.runtime.spy.sections.ActiveMenuSection.createActionContributionItemText(ActiveMenuSection.java:169) at org.eclipse.pde.internal.runtime.spy.sections.ActiveMenuSection.createActionContributionItemText(ActiveMenuSection.java:169) at org.eclipse.pde.internal.runtime.spy.sections.ActiveMenuSection.createActionContributionItemText(ActiveMenuSection.java:169) at org.eclipse.pde.internal.runtime.spy.sections.ActiveMenuSection.createActionContributionItemText(ActiveMenuSection.java:169) at org.eclipse.pde.internal.runtime.spy.sections.ActiveMenuSection.createActionContributionItemText(ActiveMenuSection.java:169) at org.eclipse.pde.internal.runtime.spy.sections.ActiveMenuSection.createActionContributionItemText(ActiveMenuSection.java:169) at org.eclipse.pde.internal.runtime.spy.sections.ActiveMenuSection.createActionContributionItemText(ActiveMenuSection.java:169) at org.eclipse.pde.internal.runtime.spy.sections.ActiveMenuSection.createActionContributionItemText(ActiveMenuSection.java:128) at org.eclipse.pde.internal.runtime.spy.sections.ActiveMenuSection.scan(ActiveMenuSection.java:104) at org.eclipse.pde.internal.runtime.spy.sections.ActiveMenuSection.build(ActiveMenuSection.java:62) at org.eclipse.pde.internal.runtime.spy.dialogs.MenuSpyDialog.createDialogArea(MenuSpyDialog.java:96) at org.eclipse.pde.internal.runtime.spy.dialogs.MenuSpyDialog.createContents(MenuSpyDialog.java:69) at org.eclipse.jface.window.Window.create(Window.java:431) at org.eclipse.pde.internal.runtime.spy.handlers.MenuSpyHandler.handleEvent(MenuSpyHandler.java:91) at org.eclipse.swt.widgets.EventTable.sendEvent(EventTable.java:84) at org.eclipse.swt.widgets.Display.filterEvent(Display.java:1227) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:1001) at org.eclipse.swt.widgets.Display.runDeferredEvents(Display.java:3917) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:3510) at org.eclipse.ui.internal.Workbench.runEventLoop(Workbench.java:2404) at org.eclipse.ui.internal.Workbench.runUI(Workbench.java:2368) at org.eclipse.ui.internal.Workbench.access$4(Workbench.java:2220) at org.eclipse.ui.internal.Workbench$5.run(Workbench.java:500) at org.eclipse.core.databinding.observable.Realm.runWithDefault(Realm.java:332) at org.eclipse.ui.internal.Workbench.createAndRunWorkbench(Workbench.java:493) 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:367) 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:611) at org.eclipse.equinox.launcher.Main.basicRun(Main.java:566) at org.eclipse.equinox.launcher.Main.run(Main.java:1363) at org.eclipse.equinox.launcher.Main.main(Main.java:1339)
Created attachment 156061 [details] getSuperclass() could return null (and that wasn't checked)
I've created a new patch for this bug as it appears that the real reason was that getSuperclass() could return null (and this situation was never checked -- thus resulting in the NPE).
done. > 20100303 Thanks for the patch.
