Description

In addition to the CasualDiff exception (see attached log), in the java file a chunk of source gets copied to the fix location.

Attached tiny project that reproduces the problem.

   enable "Use @NbBundle.Messages" hint
2. unzip sources; open OptionsPlayHackCasualDiff in IDE
3. open file OptionsPlayHackOptionsPanelController.java

         keywords = "#OptionsCategory_Keywords_OptionsPlayHack",
   

   and accept the hint "Use NbBundle.Message"
