Created attachment 205544 [details] Screen shot of new icons eclipse.buildId=I20111018-2000 I updated to this build and some new icons appears in my toolbar. I didn't know what they were and they didn't have any hover-help so I clicked on them. An NPE resulted. 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.invoke(InjectorImpl.java:209) at org.eclipse.e4.core.contexts.ContextInjectionFactory.invoke(ContextInjectionFactory.java:123) at org.eclipse.e4.core.commands.internal.HandlerServiceImpl.executeHandler(HandlerServiceImpl.java:161) at org.eclipse.e4.ui.workbench.renderers.swt.HandledContributionItem.executeItem(HandledContributionItem.java:717) at org.eclipse.e4.ui.workbench.renderers.swt.HandledContributionItem.handleWidgetSelection(HandledContributionItem.java:622) at org.eclipse.e4.ui.workbench.renderers.swt.HandledContributionItem.access$6(HandledContributionItem.java:606) at org.eclipse.e4.ui.workbench.renderers.swt.HandledContributionItem$3.handleEvent(HandledContributionItem.java:565) at org.eclipse.swt.widgets.EventTable.sendEvent(EventTable.java:84) at org.eclipse.swt.widgets.Display.sendEvent(Display.java:4129) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:1457) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:1480) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:1465) at org.eclipse.swt.widgets.Widget.notifyListeners(Widget.java:1270) at org.eclipse.swt.widgets.Display.runDeferredEvents(Display.java:3975) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:3614) at org.eclipse.e4.ui.internal.workbench.swt.PartRenderingEngine$9.run(PartRenderingEngine.java:972) at org.eclipse.core.databinding.observable.Realm.runWithDefault(Realm.java:332) at org.eclipse.e4.ui.internal.workbench.swt.PartRenderingEngine.run(PartRenderingEngine.java:888) at org.eclipse.e4.ui.internal.workbench.E4Workbench.createAndRunUI(E4Workbench.java:90) at org.eclipse.ui.internal.Workbench$3.run(Workbench.java:565) at org.eclipse.core.databinding.observable.Realm.runWithDefault(Realm.java:332) at org.eclipse.ui.internal.Workbench.createAndRunWorkbench(Workbench.java:520) 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:352) 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:624) at org.eclipse.equinox.launcher.Main.basicRun(Main.java:579) at org.eclipse.equinox.launcher.Main.run(Main.java:1431) Caused by: java.lang.NullPointerException at org.eclipse.debug.internal.ui.contexts.DebugContextManager.createService(DebugContextManager.java:136) at org.eclipse.debug.internal.ui.contexts.DebugContextManager.getContextService(DebugContextManager.java:195) at org.eclipse.debug.ui.actions.DebugCommandAction.getDebugContextService(DebugCommandAction.java:291) at org.eclipse.debug.ui.actions.DebugCommandAction.getContext(DebugCommandAction.java:236) at org.eclipse.debug.ui.actions.DebugCommandAction.run(DebugCommandAction.java:253) at org.eclipse.debug.internal.ui.commands.actions.DebugCommandActionDelegate.run(DebugCommandActionDelegate.java:70) at org.eclipse.debug.internal.ui.commands.actions.DebugCommandActionDelegate.runWithEvent(DebugCommandActionDelegate.java:79) at org.eclipse.ui.internal.handlers.ActionDelegateHandlerProxy.execute(ActionDelegateHandlerProxy.java:285) at org.eclipse.ui.internal.handlers.E4HandlerProxy.execute(E4HandlerProxy.java:68) 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.e4.core.internal.di.MethodRequestor.execute(MethodRequestor.java:56) ... 37 more
I don't have problems hitting the 'Terminate' item but do get an error like DJ's if I hit 'Suspend'. I get this NPE first before the error in comment 0 though. java.lang.NullPointerException: A handle object may not have a null identifier at org.eclipse.core.commands.common.HandleObjectManager.checkId(HandleObjectManager.java:55) at org.eclipse.core.commands.CommandManager.getCommand(CommandManager.java:544) at org.eclipse.ui.internal.commands.CommandService.getCommand(CommandService.java:146) at org.eclipse.ui.internal.handlers.CommandLegacyActionWrapper.setActionDefinitionId(CommandLegacyActionWrapper.java:356) at org.eclipse.debug.internal.ui.commands.actions.DebugCommandActionDelegate.init(DebugCommandActionDelegate.java:54) at org.eclipse.ui.internal.handlers.ActionDelegateHandlerProxy$2.run(ActionDelegateHandlerProxy.java:459) at org.eclipse.core.runtime.SafeRunner.run(SafeRunner.java:42) at org.eclipse.ui.internal.handlers.ActionDelegateHandlerProxy.initDelegate(ActionDelegateHandlerProxy.java:478) at org.eclipse.ui.internal.handlers.ActionDelegateHandlerProxy.loadDelegate(ActionDelegateHandlerProxy.java:596) at org.eclipse.ui.internal.handlers.ActionDelegateHandlerProxy.execute(ActionDelegateHandlerProxy.java:265) at org.eclipse.ui.internal.handlers.E4HandlerProxy.execute(E4HandlerProxy.java:68) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:601) at org.eclipse.e4.core.internal.di.MethodRequestor.execute(MethodRequestor.java:56) at org.eclipse.e4.core.internal.di.InjectorImpl.invokeUsingClass(InjectorImpl.java:228) 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.executeHandler(HandlerServiceImpl.java:161) at org.eclipse.e4.ui.workbench.renderers.swt.HandledContributionItem.executeItem(HandledContributionItem.java:717) at org.eclipse.e4.ui.workbench.renderers.swt.HandledContributionItem.handleWidgetSelection(HandledContributionItem.java:622) at org.eclipse.e4.ui.workbench.renderers.swt.HandledContributionItem.access$6(HandledContributionItem.java:606) at org.eclipse.e4.ui.workbench.renderers.swt.HandledContributionItem$3.handleEvent(HandledContributionItem.java:565) at org.eclipse.swt.widgets.EventTable.sendEvent(EventTable.java:84)
The 'Suspend' action doesn't have this problem because its action actually defines a proper action definition id in its constructor, see TerminateCommandAction.
(In reply to comment #2) > The 'Suspend' action doesn't have this problem because its action actually > defines a proper action definition id in its constructor, see > TerminateCommandAction. If Debug sets action definition ids for all its actions then these NPEs would theoretically just all disappear. See bug 361448.
Created attachment 205567 [details] Line between icons. (In reply to comment #3) > If Debug sets action definition ids for all its actions then these NPEs would > theoretically just all disappear. See bug 361448. With the fix to bug 361448, I don't see the NPE anymore, but the behavior is still somewhat different than in 3.x: 1) The actions are enabled until I select them once. 2) There's a strange while line between the step icons (see screenshot). 3) I don't get tooltips on any toolbar items.
(In reply to comment #4) > 3) I don't get tooltips on any toolbar items. That may be fixed by bug 361415.
(In reply to comment #4) > 3) I don't get tooltips on any toolbar items. If you're on Linux you may also be hitting bug 354126.
(In reply to comment #4) > 1) The actions are enabled until I select them once. Opened bug 361561 for this. > 2) There's a strange while line between the step icons (see screenshot). And opened bug 361562 for this other one. Will leave this original bug open as I'm not sure if we need to be wiring our actions in a different way to tolerate the originally null action definition ids or if the programming model that Debug is using is an unsupported path.
This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet. If you have further information on the current state of the bug, please add it. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant. If the bug is still relevant, please remove the "stalebug" whiteboard tag.
