Can't remove the_end

Hi I have been trying for a couple of days now to remove the end world from my server as it is pointless and just wasting precious resources. I have edited the bukkit.yml to allow the end: false both inside and outside of the craftbukkit.jar, i have deleted the world folder but still it just regenerates a new one everytime i restart the server. Am I missing something here? I'm also using multiverse but that shouldnt have any effect as i also remove all mention of the end world from there as well???

Has anyone else tried to disable the end?

I've tried it on CB builds 1713,1714,1768,1769 and 1774 but it makes no difference.

 

Open the bukkit.yml with notepad++ or another sinful text editor.

Code:

settings:
  allow-end: true
  spawn-radius: 16
  permissions-file: permissions.yml
  update-folder: update
  ping-packet-limit: 100

You should know, what to do

 

If you read closely ^^ I've tried that already

 

Stop server. Change bukkit.yml. Start server.

 

Sorry... I suggest following codename_B's suggestion too
