When using the git inverse branch choosing strategy (to exclude named branches) and polling a git repo, I see the following NullPointerException in the Git Polling Log:

The project config is attached to this ticket:
Unable to embed resource: config.xml of type application/xml
I believe the cause is git plugin revision 4fc7f44. This NPE occurs in version 2.0.3 of the plugin but does not in version 2.0.1. (I have not tested 2.0.2, but I suspect it behaves the same as 2.0.3.)
A possible workaround is to enable the "Force polling with workspace" option (see JENKINS-21264), but I have not confirmed if this works.
Proposed fix in GitHub pull request #208.
