I suggest putting the Minecraft_server.jar into a new, completely empty folder, and running it from there. Let it generate a world for itself, rather than using one from 1.8.1.
Replacing your other .jar with this one is going to cause it to load the same settings, worlds, etc. which could cause any number of bugs.
I have pretty much ran this entire thing fresh, I moved everything off the server and made a fresh install. Is this a common problem? Do some servers have issues running the current pre release? Thanks in advanced.
Server, not client.
huh? i do not understand

Not. Using a jar. At least, Im sure its a jar.
