I'm working on an article that'll talk about things that PMD found on some large open source Java project - now I just need to pick a project to examine.

I guess I could scan the PMD scoreboard for the largest project and pick it... Columba is pretty good-sized (50K LOC as measured by JavaNCSS), seems like a nifty project, and looks like it might have some things that could be fixed.

At any rate, hopefully I can send the developers a nice patch to fix whatever PMD finds. Got to contribute as well as criticize!
