Bukkit Changes:
217dc08d SPIGOT-4634: Make Inventory iteration behaviour explicit
This was a useless exception wrapper that ends up making
stack traces harder to read as well as the JVM cutting off
the important parts
Nothing catches this exception, so its safe to just get rid
of it and let the REAL exception bubble down
