Multiverse Error

I am getting this every now and then.
I updated to the latest dev. builds of Multiverse-Core and Multiverse-Portals to see if it would go away, but it hasn't.

Code:

I am running CraftBukkit++ btw, which shouldn't cause any problems.

My console reads from bottom to top instead of top to bottom btw.
