    Hey members of Bukkit!
    I'm having problems with my Bukkit server. It is running the 1.6.2 development build. When I go to start my server up, it crashes with this error.

    Code:

  2. It crashes on

    so according to the GitHub file, it's a problem with saving the world. Maybe delete the world folder, and regenerate it again? This should fix your problem.

    Hmm, I'll try that. But, the world we were on had SO MUCH progress. It would really annoy me if I had to delete it.

    Yup, I tried it. No luck there...

  4. Hmm.. I guess your only option now, is to wait for the next developer build and hope it's fixed, or you can just redownload CraftBukkit.

    tomato500

    Yeah, I tried that but I'm still getting the error. What could be the problem now?
     
  6. Not sure if it'll help, but try disabling jline

    I hope I don't sound too stupid, but how do I disable JLine?

    P.S. I'm on Windows 7 64-bit
     
  8. Add this, without the quotes, to the end of the .bat/.sh/.cmd "--nojline"
    eg.
    java -Xmx1024M -jar craftbukkit.jar -o true --nojline

    This happened to me too - Check your server.properties for damage.
    Mine (somehow) got wiped; deleting it fixed it for me.

    I had this problem too. Surprisingly, when I renamed the folder in which my server was in to a shorter name, it worked. Not sure if this is true, but it worked for me :p

    Alright guys, I figured this out.

    I deleted everything from the folder EXCEPT for the CraftBukkit.jar and the start.bat.

    Then I launched the server, and believe it or not, it worked!

    Thank you guys for all your tips, and I hope this helps everyone who is having this problem.

    (But whatever caused the problem is still a mystery)
