I'm always careful to make sure that all my charts are encrypted, so it's great that jFreeChart pulls BC as a dependency.

Looks like a handy tool, especially being able to predictably stall programs for multi-threaded testing. Force the JVM to behave like those theoretical "thread A does this then thread B does this" interleave diagrams that show the potential for deadlock/whatever? Sweet .
