Bug 176441 [Markers] NPE while refreshing the problem view
I got this exception using I20070228-0930. No steps to reproduce. It seems to happen when refreshing the problem view. java.lang.NullPointerException at org.eclipse.ui.views.markers.internal.MarkerAdapter.buildAllMarkers(MarkerAdapter.java:251) at org.eclipse.ui.views.markers.internal.MarkerView.updateForContentsRefresh(MarkerView.java:570) at org.eclipse.ui.views.markers.internal.MarkerView$MarkerProcessJob.run(MarkerView.java:151) at org.eclipse.core.internal.jobs.Worker.run(Worker.java:58)
