      Description

      When connecting to a LAN world that is rather large, the host will send huge network packets to its clients, and there appears to be a 'protocol maximum,' which makes properly connecting to large LAN worlds impossible.

      Steps to Reproduce:
      1. Host a LAN world that is large and well played on. (E.g. a well-played survival world, or an adventure map).
      2. When other players attempt to join, they will get an error message like this:
      Internal Exception: io.netty.handler.codec.DecoderException: Badly compressed packet - size of 2487995 is larger than protocol maximum of 2097152

      It is worth noting that you can properly connect to a LAN world if the world has just recently been created, probably because it is newly generated and therefore is not sending very many network packets.

      This problem must be fixed. It is not a problem with the network we were using - we tried it at two different places and came up with the same problem. Therefore it must be a problem with Minecraft.
