Build Identifier: Version: Indigo Service Release 1 Build id: 20110916-0149 The Method PartStack#smartUnzoom uses the return-value of the Methode LayoutPartStack#getContainer without a null check. The javadoc of this method says that the return-value can be null... This leads sometimes to an NPE. Reproducible: Sometimes
Could you please attach your logfile with the NPE? PW
Created attachment 210298 [details] Trace of the NPE (In reply to comment #1) > Could you please attach your logfile with the NPE? > > PW Added the trace.
Meanwhile I could reprodruce the problem: preconditions: We have an RCP that don't restore editors on startup. We have good reasons to do this. Steps: 1. Start an RCP that meets the preconditions. 2. Open Views so that you have one or more partstacks. 3. Open an editor an maximize it. 4. shutdown the RCP (without closing the editor!) 5. Restart the RCP (the partstacks are minimized and no editors are open). 6. Open an editor. 7. Close the editor. 8. The workbench calls the Method PartStack#smartUnzoom() and throws the mentioned NPE.
Additional Info The #dispose Method of the mentioned editor don't get called, so we have an resource-leak in the case the error occurs.

This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet. If you have further information on the current state of the bug, please add it. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant. -- The automated Eclipse Genie.
