I had this exact problem yesterday when I updated java. It's something to do with intel gen 1 and gen 2 processors and any java newer than java 8 update 60. So if his graphics processor is intel integrated graphics and his CPU gen 1 or gen 2, he'll need to download java 8 update 51 instead of 65.

I'm pretty sure this also means he may need to update his processor's graphics. You can simply go to the processor manufacturer's website, and find an update section.

I don't feel like being the one to mess with my java version and update my graphics driver right now since I spent a good hour or more yesterday trying to fix it when it stopped working. So if the OPs friend tests this, and this is the case and all it takes to get it to work with the latest java is a driver update then please make a post and then I'd like to update java myself too.

 

I did the Windows "Scan for drivers update" thing and it told me that I had the latest driver for my processor, but we all know how good Windows is at things like that so it might have lied.

Windows honestly will only truly detect updates for an ATI graphics card. That's why it's important to go to the manufacture's website to check for updates.

Is this GL error repeatable? I get occasional GL crashes on my own machine, especially after switching contexts / full-screen mode etc. Restarting the launcher et al usually gets around the problem. Rebooting takes care of my more persistent conditions.

When I read up on the error it said that the new minecraft launcher, because of the fact it comes with java supplied or something, doesn't have this problem. However I was having this problem when launching in a dev environment and I suppose the issue would exist if they are using the old launcher and not the new one.
