I'm trying to use the infinispan connector. Due to https://jira.jboss.org/jira/browse/ISPN-355 I'm using Infinispan 4.1 Alpha 1 for my testing. After a bit of tinkering, I got it running except that I now get the following exception:

Caused by: org.infinispan.marshall.NotSerializableException: org.modeshape.graph.connector.map.DefaultMapNode
Caused by: an exception which occurred:

Doesn't seem quite right that DefaultMapNode is not serializable.
