As I was testing the new features of the snapshot 14w32d, I found an underwater temple. Upon getting close, the game froze and the Launcher said that classfile CodecJOrbis has an error regarding the inputstream in the initialize method, more specifically the sound for the mob guardian (attack loop). As the game didn't crash I have no report but I do have the Game Output Error:

"Error in class 'CodecJOrbis'
Unable to acquire inputstream in method 'initialize'.

There is also a visual copy of this with a dual screen view of both the launcher and the distance from the temple while frozen.
