I can reproduce the bug. Thats kind of strange as the author of
jfreechart did some nice graphics with it running on a classpath based
VM as he is a GNU classpath submitter too. It all looked fine. He also
did several runs with statcvs and submitted patches to statcvs to make
it work with free runtimes.

I think this just a small issue in GNU classpath that can be easily fixed.
Can you please file a bug with testcase into GNU classpath bugzilla?
