Badly compressed packet disconnect loop

The bug

Shulkers filled with completely full written books can cause a player to become stuck in an infinite disconnect loop. This is impossible to get out of without editing your player.dat or using a modified client.

Steps to reproduce

  1. Start a (local) server
  2. Join the server
  3. Open a book and quill and fill every page completely (I did this by pasting ð everywhere)
  4. Sign the book
  5. Place down a shulker
  6. Copy the book by crafting it with a book and quill
  7. Repeat step 6 until you have the shulker filled completely with books
  8. Fill 6 more shulkers with the same books
  9. Pick up the 7 shulkers
  10. Place any type of container (chest, ender chest, etc.)
  11. Open said container
    → Internal Exception: io.netty.handler.codec.EncoderException: java.lang.IllegalArgumentException: Packet too big (is 10388519, should be less than 8388608): qi@2ab7a9f4
