Starting Minecraft then loading and generating a singleplayer or multiplayer world on any server, you would be able to play for a brief time, but then it would crash giving either the ConcurrentModificationException or NullPointerException. For the brief time it was playing, the subtitles would constantly play the block broken sound, even when I am not breaking any blocks.
