Kicked out of a server when hit by a shurker.

While playing on the snapshot server!

After getting shot by a shurker, I started to levitate.
After a couple of second of levitation, you get kicked out of the server with this message:

Internal Exception: io.netty.handler.codec.decoderException: com.google.gson.JsonSyntaxException: com.google.stream.MalformedJsonException: Use JsonReader.setLenient(true) to accept malformed JSON at line 1 column 2
