Bug 142785 NavigatorSaveablesServices NPEs on shutdown
On Build id: I20060505-1306: The following exception was encountered on shutdown, and encountered multiple times (about 20). I'm not sure I have a scenario that can reproduce this, but there were many more Navigator extensions than base platform (roughly 20). I think by the time this was reached, the Project Explorer had been disposed. !ENTRY org.eclipse.osgi 4 0 2006-05-19 11:21:38.993 !MESSAGE An unexpected runtime error has occurred. !STACK 0 java.lang.NullPointerException at org.eclipse.ui.internal.navigator.NavigatorSaveablesService.computeSaveables(NavigatorSaveablesService.java:216) at org.eclipse.ui.internal.navigator.NavigatorSaveablesService.recomputeSaveablesAndNotify(NavigatorSaveablesService.java:374) at org.eclipse.ui.internal.navigator.NavigatorSaveablesService.handleBundleStopped(NavigatorSaveablesService.java:457) at org.eclipse.ui.internal.navigator.NavigatorSaveablesService.bundleChanged(NavigatorSaveablesService.java:100) at org.eclipse.ui.internal.navigator.NavigatorPlugin$1.bundleChanged(NavigatorPlugin.java:35) at org.eclipse.osgi.framework.internal.core.BundleContextImpl.dispatchEvent(BundleContextImpl.java:1206) at org.eclipse.osgi.framework.eventmgr.EventManager.dispatchEvent(EventManager.java:189) at org.eclipse.osgi.framework.eventmgr.EventManager$EventThread.run(EventManager.java:291) 11
