sigsegv when trying to run Juniper VPN

Above error came from attempting to start the jar manually as the browser initiates it and then the window disappears.
/usr/lib/jvm/java-6-openjdk-i386/jre/bin/java -jar NC.jar -u XXXXXXXX -p XXXXXXXX -h XXXX.XXXX.XXXX

Status changed to 'Confirmed' because the bug affects multiple users.

I got the same error with jre1.7.0_51 from Oracle:

@Dan Shea: Did you find a solution? When I try to connect to the Juniper VPN of my company via the browser, it behaves the same - the connection window is initiated and immediately after that, an error message appears stating that it disconnected.

Same error with OpenJDK 7.0
