Signs Bug

Your username: 3722

In which minigame/server does the bug occur: Creative (may not be the only one).

Detailed description of bug: When you type {} into a sign, it will kick you from the server.

 

I went onto creative to try this and it did not kick me, I think it may just be you.

 

This seems to be a bug that occurs with versions higher then 1.8.
Though I'm not sure if this is server sided, as it isn't a kick for doing this specifically, but it just says
"[Proxy] Lost connection to server"

 

I've gotten other kick messages as well, including the javaException one.
