Problem/Bug CraftBukkit Server suddenly not working?

Hey all, I set up my CraftBukkit server a little while ago and everything's been fine up until today; I double-click on the Java file to start the server, but when I go into MC and try to connect it says that it can't connect to the server.

Also this is the latest log for the CraftBukkit server:

Code:

I'm not sure what's going on. I haven't changed anything about the server to make it do this, just suddenly can't be connected to. Hopefully someone can help!
