I get the same message and kept getting kicked from my server but it seemed like it only happened when I approached a parrot, then I would get kicked and rejoin and kicked like 2 seconds later saying: Internal Exception io.netty.handler.codec.decoderexception java.lang.nullpointerexception. After the parrot would be killed I had no issues but then for the heck of it I went on creative and spawned a parrot and was immediately disconnected. I am playing on a 1.7.2 generated world but have never had this issue.
