Plugin Help Plugin Not Enabling Properly

Ignore the name of the plugin. I can send the jar if needed to decompile and review all the code. I get the following errors!

Code:

[22:53:21] [Server thread/INFO]: [StaffMode] Enabling StaffMode v1.0
[22:53:21] [Server thread/ERROR]: Error occurred while enabling StaffMode v1.0 (Is it up to date?)

Bump - still need help

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

add the class commands/stafflist to this page as the error is related to that.

 

1.: Don't learn from theBcBroz, they teach bad habits
2.: No need for enable/disable messages, bukkit already handles that for you
3.: Don't steal minecraft's logger, use simply getLogger
4.: You didn't posted the correct class, the problem is in StaffList

 

I would say that you try to access to "staff" (l43) to set it an executor.
The problem is that "staff" does not exist.
It return null and you have an error
