Launcher throwing exception in minecraft main thread

[noctem9]

Ubuntu 11.10 x64

$ java -version

java version "1.7.0_03"

Java SE Runtime Environment (build 1.7.0_03-b04)

Java HotSpot 64-Bit Server VM (build 22.1-b02, mixed mode)

Launcher downloads and sets everything up. When it fires up the Minecraft client I get a white screen where the Mojang splash should be and this error log:

Any ideas on how to fix this?

Thanks in advance.
