      The bug

      When naming a previously unnamed item of any type, when I attempt to shift-click it out of the anvil, the game crashes. This happens more often when the item name is very long or contains non-letter characters, such as - or +.

      How to reproduce

      1. Get an anvil and a diamond sword.
      2. Give yourself some xp. 
        /xp add @s 500
      3. Put the diamond sword into the anvil, and rename the sword to: 
        ABC123456789101112

        → Your game crashes.
