A fatal error has been detected by the Java Runtime Environment. EXCEPTION_ACCESS_VIOLATION

This is a bug inside JRE. You can do nothing about this, just send a bug report to the link provided:

Try to use 32-bit version instead of 64. Try to use another JRE version (not 6.0_27-b07).

Just dropping by to tell that I got the same error and it went away when I simply rebooted the computer. Try restarting the computer especially when everything was working fine earlier.
