Well I am not able to reproduce it in new workspace on the HEAD with no patch applies. Now all I can see is NPE in findFilePath (note again that this is HEAD with no patch applied).

Let me post stack trace here if you are interested. I'll file a bug if I am able to reproduce reliably.

Maybe I missed some.
