Comment 2 Tomas Stupka 2011-06-09 15:05:44 UTC 
the NPE is a aftereffect of a previous error:
INFO [org.netbeans.core.startup.layers.BinaryFS]: value = org.netbeans.modules.git.GitVCS from Services/VersioningSystem/org-netbeans-modules-git-GitVCS.instance
java.lang.ClassNotFoundException: org.netbeans.modules.git.GitVCS

org.netbeans.modules.git.GitVCS couldn't be loaded even if the git module was listed on startup

- did you do anything with the Git module - deactivated or uninstalled?
- do you have some mixed repositories? e.g. a cvs checkout under a folder containing a .git folder?

Comment 4 misterm 2011-06-09 15:14:26 UTC 
I've updated it.
Comment 5 Tomas Stupka 2011-06-09 15:21:50 UTC

containing a .git folder?
Comment 6 misterm 2011-06-09 15:23:27 UTC 
I have parallel checkouts, but not contained within each other. For instance:

- parent/cvs-based-project1
- parent/cvs-based-project2
- parent/git-based-project1
Comment 7 Tomas Stupka 2011-06-09 15:25:12 UTC 
did you get the exception in the same nb session in which you updated the
plugin?
Comment 8 misterm 2011-06-09 15:26:04 UTC 
Hmmm, I think so, can't tell for sure now... I had to do a restart today, so I can't remember.
Comment 9 Tomas Stupka 2011-06-09 15:46:11 UTC 
fixed the NPE 
core-main #a852fae8816f
Comment 10 Tomas Stupka 2011-06-10 17:46:29 UTC 
hm, not sure at the moment what might have been the cause for this, but there were recently some version misconfigurations (fixed in #4d55725576d5) so could be that.

the NPE is handled and also added more log #a852fae8816f in case similar behavior reappears

will close for now
