[Rxtx] Port Locking / JVM Crashing

Trent is right I used the new Red Hat kernel 2.6 with rxtx 2.1-7
(final), I wasn't able to completely able to eliminate the problem but
migrating to the latest kernel surely helped. I still see some locks but
after many many cycles of opening and closing different comm ports.

Thank you for your response. When I tried the latest-and-greatest, I
did compile it by hand as the libraries I'm using depend on the
javax.comm.* package structure and not the gnu.io.*
Does the 'contrib/ChangePackage.sh' script still work for rxtx-2.1-7r2?
If not, is there some javax.comm pass-through wrapper for the gnu.io
packages? That's the only think I can think that might have caused me
Otherwise, I'll try it again and if I still run into problems, I'll let
you know more specifically what problems I have.
Thanks again for your help.
