Poll SCM not working

[bwebster]

We are using the Poll SCM option to detect changes and trigger a build. We have the polling schedule set to * * * * *. However, Hudson doesn't detect any changes. Looking in the scm-polling.log file for a job shows this:

Seems like GitUtils.getPollEnvironment() tries to upcast the TaskListener to a BuildListener, with the NodeProperty.setUp() method requires.
