I have both vm's installed and I can only reproduce the problem with the
IBM's JRE.
I believe you can download the IBM JRE at
http://www.ibm.com/developerworks/java/jdk/.
FWIW here are the versions that I've tried (on Linux) :
Sun : java full version "1.5.0_07-b03"
IBM : java full version "J2RE 1.5.0 IBM Linux build pxi32dev-20070511(SR5)"

I'll investigate as well. Can I download IBM's vm from somewhere?
