My friend has an issue with his Minecraft client. When he starts it up, it crashes right when it loads. This is the crash message he gets:

He gets this with both Minecraft with and without Optifine. This doesn't happen on any versions before 1.8. We need help.

Thanks bro! On skype with my friend right now!
