Frequently (but not always) when hitting any kind of hittable entity, such as a boat or a skeleton or enderman, or receiving damage from any mob or player, the game will freeze and become "Not Responding", and the user must kill the program with the Task Manager. No crash reports result.

HOWEVER, this bug does NOT occur when the glitch which causes the sound system to be disabled occurs, which happens frequently after restarting the game from this crash. This leads me to think it has to do with the sound when the player deals or receives damage.

This is extremely annoying to me as I have almost died multiple times to it on my survival multiplayer server, and when it happens once it tends to happen repeatedly, so I end up playing for like a minute between restarts at times.

EDIT:
Looking around on the internet, this appears to be a fairly rare bug, as I have only found two posts on the internet that seem to indicate similar behavior. It may be hard to reproduce. Editing in my system specs in more detail.

EDIT 2:
More detailed steps to reproduce:

1. Make sure the sound is working normally.
2. Spawn a bunch of boats.
3. Hit them until it freezes.

Note: This is just one of many possible ways to reproduce the bug.

EDIT 3: Attempted updating LWJGL
Updating to LWJGL 2.9.3 from 2.9.1 had no effect.
