Bug 85350 [Markers] [Progress] NoClassDefFoundError from job running during shutdown
i200502150800 Got the following exception running Core UI application startup performance tests (the test just exits once the workbench is alive, so it is a very short session). I did not verify the source code, but it seems the runtime plug-in may have already been stopped when the job in question started doing its work. java.lang.NoClassDefFoundError: org/eclipse/core/runtime/jobs/ILock at org.eclipse.ui.views.markers.internal.TableContentProvider.cancelPendingChanges(TableContentProvider.java:342) at org.eclipse.ui.views.markers.internal.TableView.haltTableUpdates(TableView.java:94) at org.eclipse.ui.views.markers.internal.MarkerView.internalRefresh(MarkerView.java:188) at org.eclipse.ui.views.markers.internal.MarkerView.access$3(MarkerView.java:181) at org.eclipse.ui.views.markers.internal.MarkerView$3.run(MarkerView.java:281) at org.eclipse.ui.views.markers.internal.RestartableJob$2.run(RestartableJob.java:85) at org.eclipse.core.internal.jobs.Worker.run(Worker.java:67)
