What I expected to happen was being able to play minecraft normaly without it stopping after just one minute. What actually happened was that Minecraft did stop after just one minute and with the following error message.

I downloaded the new launcher with the 64 bit java version. Then I start a world and after a minute or so it stops and I get the crash report.
