Description MackSix 2013-01-16 14:02:11 UTC
This bug was originally marked as duplicate of bug 193654, that is already resolved. This bug is still valid, so this seems to be another bug, but it might be related.

VM: Java HotSpot(TM) 64-Bit Server VM, 23.6-b04, Java(TM) SE Runtime Environment, 1.7.0_11-b21
OS: Windows 7

User Comments:
MackSix: 1. Renamed 2 packages 2 times. 2. Closed the project and reopened it. 3. Uno rename once, then Undo again. This exception was thrown.

I can't reproduce it now. The other day I was doing the same thing and had another NullPointerException reported here: http://netbeans.org/bugzilla/show_bug.cgi?id=224777
Comment 3 Jaroslav Tulach 2013-01-17 08:12:38 UTC
I have added an earlier check into the code, but the root problem is 

refactoring.plugins.FileRenamePlugin$RenameFile.undoChange(FileRenamePlugin.java:135)

calling DataObject.rename(null). After my 5139b6625896 change you'll get IAE.

Reported for 7.3.x or earlier, no new info since then -> closing as worksforme, please reopen in case you see it.
