I have an EditorPart. In the overridden setBusy I do a setPartName. This works, but logs an NPE: !ENTRY org.eclipse.ui.workbench 4 0 2013-10-09 14:17:51.558 !MESSAGE An unexpected exception was thrown. !STACK 0 java.lang.NullPointerException at org.eclipse.ui.internal.ide.application.IDEWorkbenchWindowAdvisor$1.propertyChanged(IDEWorkbenchWindowAdvisor.java:107) at org.eclipse.ui.part.WorkbenchPart.firePropertyChange(WorkbenchPart.java:129) at org.eclipse.ui.part.WorkbenchPart.setTitle(WorkbenchPart.java:311) at org.eclipse.ui.part.EditorPart.setDefaultTitle(EditorPart.java:294) at org.eclipse.ui.part.WorkbenchPart.setPartName(WorkbenchPart.java:390) at org.eclipse.ui.part.EditorPart.setPartName(EditorPart.java:268) at com.priint.gui.editors.report.ReportEditor.showBusy(ReportEditor.java:142) at com.priint.gui.editors.report.ReportEditor$2.completed(ReportEditor.java:81) at org.eclipse.swt.browser.IE$7.handleEvent(IE.java:620) at org.eclipse.swt.ole.win32.OleEventTable.sendEvent(OleEventTable.java:55) at org.eclipse.swt.ole.win32.OleEventSink.notifyListener(OleEventSink.java:152) at org.eclipse.swt.ole.win32.OleEventSink.Invoke(OleEventSink.java:120) at org.eclipse.swt.ole.win32.OleEventSink.access$1(OleEventSink.java:97) at org.eclipse.swt.ole.win32.OleEventSink$1.method6(OleEventSink.java:71) at org.eclipse.swt.internal.ole.win32.COMObject.callback6(COMObject.java:119) at org.eclipse.swt.internal.win32.OS.DispatchMessageW(Native Method) at org.eclipse.swt.internal.win32.OS.DispatchMessage(OS.java:2549) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:3757) at org.eclipse.e4.ui.internal.workbench.swt.PartRenderingEngine$9.run(PartRenderingEngine.java:1113) at org.eclipse.core.databinding.observable.Realm.runWithDefault(Realm.java:332) at org.eclipse.e4.ui.internal.workbench.swt.PartRenderingEngine.run(PartRenderingEngine.java:997) at org.eclipse.e4.ui.internal.workbench.E4Workbench.createAndRunUI(E4Workbench.java:138) at org.eclipse.ui.internal.Workbench$5.run(Workbench.java:610) at org.eclipse.core.databinding.observable.Realm.runWithDefault(Realm.java:332) at org.eclipse.ui.internal.Workbench.createAndRunWorkbench(Workbench.java:567) at org.eclipse.ui.PlatformUI.createAndRunWorkbench(PlatformUI.java:150) at org.eclipse.ui.internal.ide.application.IDEApplication.start(IDEApplication.java:124) 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:354) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:181) 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:606) at org.eclipse.equinox.launcher.Main.invokeFramework(Main.java:636) at org.eclipse.equinox.launcher.Main.basicRun(Main.java:591) at org.eclipse.equinox.launcher.Main.run(Main.java:1450) at org.eclipse.equinox.launcher.Main.main(Main.java:1426)
Probably org.eclipse.ui.part.WorkbenchPart.toolTip needs to default to "" like in 3.8 PW
I pushed a simple guard in https://git.eclipse.org/r/17861 It guards against IWorkbenchPart.getTitleToolTip() not to return null. This method should actually never return null but apparently sometimes does. It is not so clear what causes this. Could be related to bug 407511.

(In reply to Peter Kullmann from comment #2) > It is not so clear what causes this. Could be related to bug 407511. Correct. I've reverted that change.
Verified in 4.4.0.I20140528-2000 (that the change has been removed)
