Error refactoring without any details
When I attempt to refactor a package or java file (in my case, a Participant), I get:
An exception has been caught while processing the refactoring 'Rename Package'.
Reason:
Exception does not provide a detail message
java.lang.NullPointerException
My RTC 4.0.5 Eclipse client log show:
!ENTRY org.eclipse.ltk.ui.refactoring 4 4 2014-12-09 20:23:59.900
!MESSAGE Exception does not provide a detail message
!STACK 0

Is this a known bug? Is there a workaround or fix?

Susan, I recently had the same thing. Whatever I did, this happened. I don't know why. I solved it by creating a new project and bringing my code over. It was a copy in the first place, so no harm done. I am not sure what the root cause was, but somehow the project was broken.
Comments So this is how i got into this mess in the first place :-) When I do a new plugin, I like to make a copy of a previous one and then refactor to rename the package and rename the java files. The copy of the project works but refactor/rename of the package and java files fail. So then I create a new package, create new files, copy/paste the contents. Since my participants only have 2 java files, it isn't too painful, but it would be alot better if I could figure out why RTC is getting the NullPointerException and fix that part. It is a brand new project (literally, just copied from an existing "working" project).

I was unable to find the root cause of this and it was a lot more wasted time trying and complaining than just recreating the project 8)
