If I open a double chest that's full with items stackable up to 64, the game freezes, in fact it makes my entire system freeze for several seconds. I can get back control after a while if I hit escape and eventually the chest closes. No difference between creative and survival modes and the method of filling the chest doesn't matter.

Steps to reproduce:

1. Fill a double chest with items stackable up to 64
2. Open it while having items in your inventory (a stack of 64 is enough), doesn't work with empty inventory.

This occurs with the bundled Java and the runtime provided by OpenJDK as well. The logs don't show anything between entering and leaving the world.
