Bug 320791 NPE on workbench shutdown
This happens for me on rc3 when shuting down: java.lang.NullPointerException at org.eclipse.e4.ui.internal.workbench.SelectionServiceImpl.notifyListeners(SelectionServiceImpl.java:192) at org.eclipse.e4.ui.internal.workbench.SelectionServiceImpl.access$3(SelectionServiceImpl.java:191) at org.eclipse.e4.ui.internal.workbench.SelectionServiceImpl$2.changed(SelectionServiceImpl.java:230) at org.eclipse.e4.core.internal.contexts.TrackableComputationExt.update(TrackableComputationExt.java:95) at org.eclipse.e4.core.internal.contexts.EclipseContext.processScheduled(EclipseContext.java:333) at org.eclipse.e4.core.internal.contexts.EclipseContext.set(EclipseContext.java:350) at org.eclipse.e4.ui.internal.workbench.swt.ShellActivationListener$2.run(ShellActivationListener.java:127) at org.eclipse.core.runtime.SafeRunner.run(SafeRunner.java:42) at org.eclipse.e4.ui.internal.workbench.swt.ShellActivationListener.activate(ShellActivationListener.java:124) at org.eclipse.e4.ui.internal.workbench.swt.ShellActivationListener.handleEvent(ShellActivationListener.java:74)
