      Description

      Ever since 1.9 up to the 1.9.1 pre-releases, when there is a lot of item entities, the item itself may despawn, but the item entity still exists causing the item entity to be invalid.
      This happening causes this on the Game Output:

      [Client thread/ERROR]: Item entity 656313 has no item?!
      [Client thread/ERROR]: Item entity 656313 has no item?!
      [Client thread/ERROR]: Item entity 656313 has no item?!

      [Client thread/ERROR]: Item entity 656313 has no item?!
      

      Here is the Game Output:

      To Reproduce:
      1. Create a world.
      2. Make lots of item entities. I usually do that by blowing up my world with TNT and Redstone Blocks.
      3. See your Game Output for any invalid item entities.
