Is it real to run Derby on DRLVM without intelligent tweaking of
Derby? I am looking forward at the moment when it is. Please, do not
hesitate to file a bug against DRLVM if you find it performing not
very well with Derby. That would be valuable!

I tried: 'java org.apache.derby.tools.sysinfo' and it produced a
quite-good output on my DRLVM snapshot, but I have no idea, how to run
the tests :)

P.S.: Congratulations, all! Today is the 0x200 day of Apache Harmony
(if I count it right:) We made a significant progress since. I love
the project! Let it keep going well! ;oP
