This is Minecraft Server 1.8 not 1.8 pre 1 or pre 2.
If you own, or have made a server in the past, you should know what to do with this.
If you have never owned or attempted to make a server, please do not ask in this thread. It would be better to make a thread in the Minecraft Support forum.
If anyone is wondering. This is the legit leaked file from SimpleServer Wrapper.
