Comment 9 torsten_paul 2011-09-28 22:30:18 UTC 
(http://statistics.netbeans.org/analytics/exception.do?id=529924)

I can recreate the problem with the following steps

1) Create new project "A" (Java Application), Create Main Class a.A
   (NetBeans opens the java file automatically)

2) Context-Menu "Rename..." project to "B", tick the "Also Rename
   Project Folder" checkbox
   (NetBeans closes the editor)

3) Open the automatically created class a.A in Java editor again

4) Context-Menu "Refactor->Rename..." the "a" package to "b"

I guess it's important to have the file open in the java editor when
doing the renames...

The exception window is only popping up a second and vanishes again,
when repeating the steps, the exception window sometimes stays visible.

This is with the 7.1beta on Linux:

Log: #193261: the OpenedEditors.visibleEditors2Files map can apparently contain several entries for one DataObject some rare cases, making sure the DO will appear only once in the getVisibleEditorsFiles().
