The bug:

If you anger an enderman (or any other mob but they don't naturally spawn in the end) and then back up to the edge of an end island and crouch over the corner of a block so you're completely over the void the mob will (usually) run away from you or leave you alone, includes creepers that could easily blow you up form that distance, or passive mobs being lead with food, but not ranged mobs like skeletons or other mobs like spiders.
