From the stack trace, looks like IBuffer#getOwner() or CompilationUnit#owner is null. Will be good to get the steps that causes this.

If I remember correctly, the last action I took before this error was thrown was double click an error message in the Problems panel that no longer existed in any file (the file still existed). I have no recollection of what I did before this.

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.
