I'm using GeoMason to make a city simulation (agents walking along roads

geo.&#8203;GeomPlanarGraph object) to find out if the graph is connected or not.

But the call to 'network.getNetwork()' causes the ClassCastException below.
You can re-create this bug in CampusWorld but putting
'network.getNetwork();' anywhere (e.g. I currently have it as the first
thing to be done after the super.start() call in the CampusWorld.start()
method). See the output from CapusWorld below.

Any ideas?

Yes, I suspect there was a subtle change to JTS that broke things, and I've committed what I hope is a fix to subversion.  Can you do me a favor and update and verify that my quick little fix works?
