The client doesn't load, and judging from the stack trace I'm probably missing some runtime library. By the way, I'm on Mint 14 and using JRE 7 if that helps. Also I ran RR on another computer (Mint 13 with JRE 6) and it worked fine.

Bump. There needs to be a solution other than to use Sun's JRE. If someone can come and attach the required JPEG libraries that would be great.

offtopic but i see me in the background :o

For some absurd reason you need to use the commerical java from the oracle website.

Thanks for the help guys. I'm on Debian Squeeze right now and I fixed the issue by using

sudo update-java-alternatives -s java-6-sun

which uses Sun's JRE instead of OpenJDK's JRE. I figure the same method could be used to fix my issue on Mint. Thanks again!
