Java error.

I don't know if it is a bug, but i'll be grateful if someone explain how to fix it.
The log in screen stays black and that message appears.

it's a bug, and this one has cropped up a few times. No known workarounds right now other than checking drivers to make sure they're properly up to date from the manufacturer. Posting system and hardware information may help. OS and ver number, Java and ver number, GPU model and driver version.

Note: this was a small report, but it is best if you copy-paste the text into your post. it makes it easier to find similar issues in the future. Anything longer would just leave the devs scratching our heads as to what exactly is in the report (and us if we're trying to help find a workaround).
