Could be I never did really dive that much into it, but the last time I 
used the IBM JDK it was for an installation I had to program against an 
RS6000 that was around half a year ago, I did not recognize a 
substantial difference in speed between both two (unlike moving from Sun 
to Blackdown where Blackdown always seems to win on the same version number)

But one thing really struck me was that there was a slight bug in the 
IBM interpreter which caused a severe error on a grammatically correct 
construct. Ok given the number of lines that really was a 1:500.000 
chance that you run into that, but it was kindof weird and left a bad 
taste in my mouth regarding the bugs.

But as I said that one was half a year ago and on an IbM 1.4.x JDK, the 
application afterwards after working around that JVM issue ran fine on 
the RS6000 which I never saw before the first install of the application.
