Please include support for JDK1.5 in upcoming releases.
I did a short test using JDK1.5 which mostly worked, but I refrained from using it because os some problems that appeared. (As it is still called "unsupported" I quickly gave up so there is nothing I can report)

Reason: We would like to make use of the "better" GC support (pause tmes etc) on SMP machines.
