If you are interested in detailed information on some of the many OS/JVM 
combinations that were actually tested for the current 10.3.1.4 release, 
please have a look at the 10.3 release page under testing:
 
http://wiki.apache.org/db-derby/DerbyTenThreeRelease#head-c6b20b58527b8de23f358548756f36e643da2e71

or more specifically:

    http://wiki.apache.org/db-derby/TenThreePlatformTesting

These are only functional test results so they don't show respective 
performance if that's what you are after.

HTH,
Thomas

Hi Yarono,

I don't think there's a stated preference for neither brand nor version 
when it comes to the JVM.

 From what I can tell the majority of development and testing seems to 
revolve around JVMs from either IBM or SUN, and all currently available 
versions seems to be used.

Release testing (and automated nightly testing) is currently run on all 
1.4, 1.5 and 1.6 JVMs AFAIK, given availablility.

Generally speaking newer JVMs tend be "bigger, faster, better", but your 
mileage may vary :)

HTH,
Thomas
