Created attachment 116328 [details] stacktrace
The reported exception took place in code that has been thoroughly rewritten since. Part of the reason was similar related problems, see e.g. http://netbeans.org/bugzilla/show_bug.cgi?id=202851 http://netbeans.org/bugzilla/show_bug.cgi?id=203291 In the current codebase (7.2dev) the problem should not be present, and accordingly I could not reproduce it, so I am closing this issue. In case of need please file a separate issue, as this one does not relate to existing code any more.
