Hi, and thank you for your time to visit this post.

 

Recently, I have been encountering a problem that's quite frustrating. When I try to load a world or join a server the game crashes and brings me to an error report. The report is as follows:

---- Minecraft Crash Report ----

// Oops.

Again, Minecraft opens fine, it's when I load a world or server. I'd appreciate any help on this, thank you. 

Update to java 7 or 8.

Thank you so much! Didn't know the solution was that simple. You're awesome man.
