Bow Duplication Bug 1.8/1.8.1-pre3

Duplicate a bow with or without enchantments infinitely.

To replicate you'll need:

• 1 zero durability bow to replicate (1 shot left)
• 1 arrow
• 1 dropper
• 1 button/lever to fire the dispenser (or a redstone clock of some sort)

Steps:

• Fire the bow and instantly change to a different slot. The bow should break but instead the object in the slot you changed to gets destroyed.
• A red zero will appear on the lower right corner of the bow and it will appear to have been fully repaired.
• Right clicking the bow or opening an inventory with it in the active slot will destroy it.
• Put the bow in a dispenser or dropper.
• Fire the dispenser/dropper and a fully repaired clone of the bow will fly out whilst the glitched bow stays in the dispensers inventory.
• The red zero on the glitched bow increments to -1. Fire again it will say -2, again: -3 etc. This can be done indefinitely for unlimited bows.
