Description

Christian actually found this bug. I am filing the JIRA on his behalf. Here's my error when running TestVertexRangeBalancer.

I identified and fixed the issue by making BasicVertex implement Configurable and making the graph state set in BasicRPCCommunications. There is one more error though that I'll try and solve before putting up a reviewboard.
