So, I have this Bukkit server (I am kind of a newb to this so don't get mad at me D and I love Bukkit. I have added all types of plugins! But, last night my server crashed and my friend skyped me asking if he was the only one who crashed. But it was the server that had crashed. I tried opening it up again but once I entered, on the console it would have a bunch of stuff about at net.minecraft.server.World stuff going ON AND ON AND ON. Then, I looked in the crash report thing and it said this,http://pastebin.com/XF9nXCw7 (The time on the paste is not accurate) I tried getting rid of a plugin 1 at a time to see if it was a plugin problem but even with NO plugins I still go the error. I decided I should re-do my server so I deleted everything and made a new world folder and it worked perfectly fine. But I worked really hard on that world. Please, if you know about this problem tell me what to do!
