I just updated my minecraft server to 15w31a, but whenever I join, it kicks me out 1-2 seconds later. I'm not sure why, but many of my players are searching for an answer. I was wondering if this affected all servers, or just mine. Thanks.

I thought after I updated my vanilla minecraft server it would be running smoothly.

This didn't happen, so I am wondering if all servers are affected, or just mine.

Steps to Reproduce:
1. Add new minecraft update, 15w31a, via jar file given from mojang.com.
2. Attempt to open up my server (or any server, I think).
3. Wait 1-2 seconds to be kicked off of said server.
