Created attachment 181721 [details] Stacktrace: NPE in DocumentMerger.doDiff I got the same exception in Helios (I20100608-0911): * Several of the open files where changed outside Eclipse * I closed all open files * Then pressed F5 (refresh) on the affected project

Are you able to provide a set of reproducible steps?
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.
