[tpm] Perl, JBoss and STDOUT

Well, recalling a solution that I used recently to repair a Java
problem, is it possible that the Java application needs more memory,
as provided by the handy -X argument? 
I also understand that the very latest Java from Sun (version 6,
release 10) is a little wobbly, and reverting to release 7 makes
things run much better. I'm not sure if this is what the 'new version
of something' refers to ..
Neither suggestion is really Perl related, but in this case wild
guesses might work. Good luck, let us know how it all turns out.
