I got the following NPE from the packages explorer when starting build N20060405-0010. A restart seems to have fixed the problem. java.lang.NullPointerException at org.eclipse.jdt.internal.ui.packageview.PackageExplorerPart.getToolTipText(PackageExplorerPart.java:852) at org.eclipse.jdt.internal.ui.packageview.PackagesFrameSource.createFrame(PackagesFrameSource.java:28) at org.eclipse.ui.views.framelist.TreeViewerFrameSource.getCurrentFrame(TreeViewerFrameSource.java:81) at org.eclipse.ui.views.framelist.TreeViewerFrameSource.getFrame(TreeViewerFrameSource.java:95) at org.eclipse.ui.views.framelist.FrameList.<init>(FrameList.java:51) at org.eclipse.jdt.internal.ui.packageview.PackageExplorerActionGroup.<init>(PackageExplorerActionGroup.java:135) at org.eclipse.jdt.internal.ui.packageview.PackageExplorerPart.makeActions(PackageExplorerPart.java:916) at org.eclipse.jdt.internal.ui.packageview.PackageExplorerPart.createPartControl(PackageExplorerPart.java:632) at org.eclipse.ui.internal.ViewReference.createPartHelper(ViewReference.java:332) at org.eclipse.ui.internal.ViewReference.createPart(ViewReference.java:197) at org.eclipse.ui.internal.WorkbenchPartReference.getPart(WorkbenchPartReference.java:566) at org.eclipse.ui.internal.PartPane.setVisible(PartPane.java:290) at org.eclipse.ui.internal.ViewPane.setVisible(ViewPane.java:525) at org.eclipse.ui.internal.presentations.PresentablePart.setVisible(PresentablePart.java:140) at org.eclipse.ui.internal.presentations.util.PresentablePartFolder.select(PresentablePartFolder.java:266) at org.eclipse.ui.internal.presentations.util.LeftToRightTabOrder.select(LeftToRightTabOrder.java:65) at org.eclipse.ui.internal.presentations.util.TabbedStackPresentation.selectPart(TabbedStackPresentation.java:394) at org.eclipse.ui.internal.PartStack.refreshPresentationSelection(PartStack.java:1147) at org.eclipse.ui.internal.PartStack.createControl(PartStack.java:623) at org.eclipse.ui.internal.PartStack.createControl(PartStack.java:531) at org.eclipse.ui.internal.PartSashContainer.createControl(PartSashContainer.java:562) at org.eclipse.ui.internal.PerspectiveHelper.activate(PerspectiveHelper.java:244) at org.eclipse.ui.internal.Perspective.onActivate(Perspective.java:832) at org.eclipse.ui.internal.WorkbenchPage.onActivate(WorkbenchPage.java:2344) at org.eclipse.ui.internal.WorkbenchWindow$6.run(WorkbenchWindow.java:2585) at org.eclipse.swt.custom.BusyIndicator.showWhile(BusyIndicator.java:69) at org.eclipse.ui.internal.WorkbenchWindow.setActivePage(WorkbenchWindow.java:2566) at org.eclipse.ui.internal.WorkbenchWindow.restoreState(WorkbenchWindow.java:1978) at org.eclipse.ui.internal.Workbench.doRestoreState(Workbench.java:2857) at org.eclipse.ui.internal.Workbench.access$14(Workbench.java:2805) at org.eclipse.ui.internal.Workbench$19.run(Workbench.java:1681) at org.eclipse.ui.internal.Workbench.runStartupWithProgress(Workbench.java:1421) at org.eclipse.ui.internal.Workbench.restoreState(Workbench.java:1679) at org.eclipse.ui.internal.Workbench.access$12(Workbench.java:1650) at org.eclipse.ui.internal.Workbench$17.run(Workbench.java:1529) at org.eclipse.core.runtime.SafeRunner.run(SafeRunner.java:37) at org.eclipse.ui.internal.Workbench.restoreState(Workbench.java:1473) at org.eclipse.ui.internal.WorkbenchConfigurer.restoreState(WorkbenchConfigurer.java:183) at org.eclipse.ui.application.WorkbenchAdvisor.openWindows(WorkbenchAdvisor.java:702) at org.eclipse.ui.internal.Workbench.init(Workbench.java:1085) at org.eclipse.ui.internal.Workbench.runUI(Workbench.java:1847) at org.eclipse.ui.internal.Workbench.createAndRunWorkbench(Workbench.java:419) at org.eclipse.ui.PlatformUI.createAndRunWorkbench(PlatformUI.java:143) at org.eclipse.ui.internal.ide.IDEApplication.run(IDEApplication.java:95) at org.eclipse.core.internal.runtime.PlatformActivator$1.run(PlatformActivator.java:78) at org.eclipse.core.runtime.internal.adaptor.EclipseAppLauncher.runApplication(EclipseAppLauncher.java:92) at org.eclipse.core.runtime.internal.adaptor.EclipseAppLauncher.start(EclipseAppLauncher.java:68) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:376) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:169) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:85) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:58) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:60) at java.lang.reflect.Method.invoke(Method.java:391) at org.eclipse.core.launcher.Main.invokeFramework(Main.java:336) at org.eclipse.core.launcher.Main.basicRun(Main.java:280) at org.eclipse.core.launcher.Main.run(Main.java:977) at org.eclipse.core.launcher.Main.main(Main.java:952)
This may have been a result of using working sets. After restart, the packages explorer was no longer in working set mode.
Dirk, can you have a look if your latest changes caused this?
Yes, they caused it. Didn't test the restart in working set mode. Got already fixed.
