https://github.com/neo4j/neo4j-java-driver is a remote API for Neo4j graph database,and it is under the Apache License, so using that (instead of Neo4j embedded) there is no reason not to revive the Neo4j extension.
Hopefully, most of the codebase from Johan at Neo Technologies can be used. Cheers -- Niclas Hedhman, Software Developer http://polygene.apache.org - New Energy for Java
