I believe this is very similar to, or perhaps the same as the incomplete bug MC-19539.

This also seems related MC-3771.

I can also confirm that this problem seems to affect MineCraft only. RuneScape for example does not have this issue despite being similarly driven by Java & Open GL.

This a thread dump generated by JStack, not sure if it will help. I've noticed that the CPU also spikes incredibly high for the game when this bug occurs. Unfortunately, my VisualVM client is refusing to function properly so I cannot provide timings at the current time.

EDIT: I don't know if this is related, but VisualVM will simply not allow me to profile my MineCraft client.

Is this still an issue in the current Minecraft Snapshot 15w45b or later? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.

Ticket resolved as incomplete, because no answer in a reasonable amount of time (1+ year), if it still happens, please update the ticket.
