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...
