The bug
This has been occurring since 14w06a. As the enderman is hostile to a player, and they get damaged by a water block, they will teleport away, but still chase the player. This causes them to be very easy to farm, especially multiple at a time.
How to reproduce
Spawn/find an enderman
Punch it to make it attack you
Jump into or in front of water blocks, so the enderman runs into them
→ Notice the enderman keep attempting to get to you, and eventually die

Also in Creative, when an Enderman touches water they will teleport away (like usual), but then run back to the spot where they took damage (as if they were hostile), take damage from the water again, and keep repeating this until they eventually die. (Not sure if this is part of this issue or a different one.)
confirmed on 14w34d
