I do think so (but if you tried someday to find something in IBM
website, you know how it is hard to find something!):
./java -fullversion
java full version "J2RE 1.3.0 IBM build ca130-20010615"
where do you expect me to file that bug? ibm? wow!
I did open a call, but via our internal helpdesk, and then via somebody
@ibm.com who does not know anything about java and aix :-( well, it
seems problem has reached more concerned persons, but I really don't
know who :}

well, I did write a sample that shows problem (I can tell more or send
code), but after a couple of hours running: I could make it alloc much
more when looping... hope this could make it hang faster.
