So, basically when a player joins, then quits, and then again joins my server crashes, but it keeps the server window open. Other connected players loose connection, and nobody can enter. The window shuts down when I try to use a command. I have no idea what causes this, and I would greatly appreciate any help.

I've provided the pastebin with the crash log here: http://pastebin.com/mtfqzEA5

Thanks for reading!
