Lukasz Lenart updated WW-2956:
------------------------------
Attachment: WW-2956-1.patch
Instead of using default constructor for FileRevision (which should be
removed), just Revision object should be created like in case of Jar file. Then
check for null is not needed any more.
> setting devMode value to "true" causes NullPointerException
