BlueJ student IDE now runs PMD (with screenshot!)

I came across BlueJ, a nifty little IDE for students who are starting to learn Java.   It's in use at a variety of educational institutions and seem to have an active community.

Anyhow, it seemed nice to write a PMD extension for BlueJ, so I knocked one out.  I announced it on the bluej-discuss list and it seems to have been downloaded a few times already.    Right now it just runs the basic and unused code rulesets, but I'll add more options as I get more feedback.

The report looks quite clunky (screenshot, just a JOptionPane.showMessageDialog), but I didn't want to do too much work on it before hearing from the BueJ folks on how best PMD should be integrated.

There's another very interesting extension called Jeliot; it shows an animation of the program execution.  It's well worth a look, here's a screenshot.  Nifty stuff!
