Salem/Java crash

[Gauteamus]

Uhh, I quite often get this error when trying to run Salem (default client). Anyone know its cause?

You need to update your video card drivers.

Note: some older cards/drivers don't support OpenGL properly. See this thread for more information: viewtopic.php?f=10&t=96. If a workaround or third party driver isn't an option, then replacing the card may be your best bet.
