Error inside Serial.<init>() driving me crazy!

I am trying to connect to Lego NXT via Bluetooth using the Serial library.
After one succesful connection, all I get now is this error message: "Error inside Serial.<init>() gnu.io.PortInUseException: Unknown Application".
Having trawled the internet for every possible solution to this problem and still getting this #€!§ error, I am finally declaring myself checkmate... *sigh*
QUESTIONS
- Does the version of RXTX (2.1-7) that ships with the current release of Processing use lock files?
- Does the version of RXTX (2.2pre2) available at http://jlog.org/rxtx-mac.html use lock files? According to this section in the RXTX wiki, releases above 2.1-7 use I/O Kit instead of lock files. If this is true, why do I need to run the supplied fixperm-217-leo.sh script to fix permissions, append group memberships and create lock directories?
- Using Terminal to check my group memberships, I am not a member of the "uucp" group after running fixperm-217-leo.sh. Even as an admin using all "sudo"s in the world, I am not able to become a member of the "uucp" group. How does this affect my use of the RXTX library? Any ideas of why I am not able to join this group?
- Using the Serial library to connect to my Arduino is succesful. Could it be that the errors are linked to my Bluetooth setup rather than RXTX?
