So, I checked all the obvious, removed the plugins I have installed, and reinstalled craftbukkit. But even when doing all that, it still has this endless loop on the command prompt. The server would let you on and everything, but for one, you wont know when someone gets on, and you cant use plugins, or even say the default commands. Someone please help? Attached is a screenshot of it, but it doesnt appropriately show how fast its actually looping. Running on a Windows 7 laptop, 64 bit. Latest java installed. 4 G RAM This problem just occurred by the way, server was working fine a hour ago.
