Todd, this sounds like version clash. You are sending in an org.neo4j.api.core.Node from your application it seems, when the new version is moved to be compliant with Neo4j 1.0-RC1 which has moved the API to org.neo4j.graphdb.Node . Try upgrading the rest of your App to Neoj4 1.0 RC1 and things should work fine again...
