Survival
With enough players online, entering a command like the following kicks all players because @a gets expanded to a list of all online players.
/me @a @a @a @a @a @a @a @a @a @a @a @a ...
This is what it looks like from the logfile.
derp lost connection: TranslatableComponent{key='disconnect.genericReason', args=[Internal Exception: io.netty.handler.codec.EncoderException: java.io.IOException: String too big (was 33145 bytes encoded, max 32767)
At this point my server has become unplayable with more than 10 people online. This issue is well-known and spreading. I expect waves of players doing this to every vanilla server.
