Whenever a fireball is spawned using the "/summon" command or through server plugins or fireball spawners the game freezes or crashes instantly. This does not happen when a ghast shoots a fireball however.

What I expected to happen was:
A fireball to spawn.

What actually happened was:
The game freezes or crashes.

Steps to Reproduce:
1. Load a survival or creative world
2. Type "/summon Fireball" in the chat
3. Game freezes
