While playing on my multiplayer server whenever i go into the nether portal my game always crashes. When I reopen minecraft and go through the portal again it does not crash.
Edit: I'm not sure if that is the right crash report or not. The client just completely closed and i had to reopen the launcher to play again.

Your Java is ancient. Please update your Java to the latest version: http://www.java.com/en/download/ .
When using a 32-bit browser on a 64-bit operating system the automatic version detection will only show the 32-bit version of Java, the 64-bit version needs to be downloaded manually: http://www.java.com/en/download/manual.jsp .
