Whitelist issue - Error after adding

Hi i hope i place this in the right place because I never was good with forums.

Anyways I am part of a server netwerk and this day after I added a player to a whitelisted server I got this error: http://pastebin.com/Hz73eQyj
The player does get added but after a restart of that server he have to be added again

It's something I never saw before and I was hoping someone here would.
Thanks already for all of your time!

You may be using an unstable version of Spigot 1.7.9. You might change to the 1.7.10 Dev version.

Thanks for the reply.
But i solved it myself already.
It was a problem within the root of the server not with the client it was running on.
The whitelist didn't had the permission to access itself so it changed that.

Thanks anyway

Have a good day
