[Rxtx] Port Locking / JVM Crashing

[Trent Jarvi]

Hi Andy

The script mostly works though it's usually used to go the other way while 
preparing rxtx 2.0 for release.  If you noticed the exception error you 
saw was a / instead of a . in the exception..

javax.comm/PortInUseException as I recall.
----------^

So its not perfect but that will not be the cause of the error you saw.
