I keep getting this weird crash when ever I go to shut down my server. I am using sponge but I don't see anything about sponge in the stack trace.

Odd, can you attempt to re create this issue with sponge uninstalled.

I haven't tried to re-create it. Every now and then when I restart the server this happens. It started happening a couple days ago. It's hard to say what's causing it.

I'll see what I can do when I get some time.
