I found a case where the inverse build strategy built the wrong branch. Perhaps this is expected behavior in this case. It is kind of an odd case.

• create git repo with master branch
• create new job cloning git repository, leave everything at the default
• build the job - builds master as expected
• create branch b1 in git repo
• change the configuration to be inverse
• wipe out the workspace
• build the job - builds master instead of b1

Here's the output of the job:

No new revisions were found; the most-recently built branch will be built again.
