Great news! Thanks for doing this, Mark.  I look forward to playing
with it soon.

As to the jtreg hack, I fiddled about with a similar short bit of
shell hackery a few months back and managed to run the JMX tests this
way.  Not a full-proof solution by any means, and I wouldn't attest to
it working well generally, but it does the job for the time being.

The spec. for the jtreg files is available online.  Was it not for a
Free version being in the works from Sun anyway, we could probably
implement a clone.

Cheers,
