Windows .jar Ultimate server runtime error

I've been testing the ultimate server on my comp (the same one that the client is running off if thats important) and I keep getting this error:

Can you post your entire log to pastebin.com and link it?

I found the problem with it. The server doesn't like you running the client and server from the same computer and using "localhost" as the connection type. Ran it from a dedicated machine for a hour or so, and I haven't had this error come up yet.
