-------------------------------------------

             Summary: Projects using bazaar mayclog the prepare queue
                 Key: CONTINUUM-2737
                 URL: https://jira.codehaus.org/browse/CONTINUUM-2737
             Project: Continuum
          Issue Type: Bug
    Affects Versions: 1.3.8
            Reporter: Brent N Atkinson


Originally reported as part of CONTINUUM-2369, it appears that there may be an issue where
projects using bazaar clog the prepare-build queue. It looks like the issue stems from an
inability to complete the working copy update tasks. 

The issue appears in the continuum logs as a {{NullPointerException}} when running the {{UpdateWorkingDirectoryFromScmContinuumAction}}:

It may be that failure to run the action results in the project staying in the build queue.
