I recognized your error almost immediately, since we encountered it in an early

I think you'll have a good result if you can switch to the 1.4.1 release!

Hey,
If you want to play with JUNG over Neo4j, you can do it via TinkerPop.

That GraphJung object is a implementation of the JUNG Interfaces and can be
