Found two source repos for this project.
The first one seems newer, but has never had a "mvn deploy" done as far as I can tell. The most recently deployed snapshot came out of the 2nd repo. This is what I'm using to determine last release.
That points back to the 2nd repo in the above list. This is the repo I'm patching against.
The 2nd repo has no project infrastructure set-up that I can find (I think there was at one point, but it may be gone). The first one has a codehaus site created with not much there.
