DataNucleus Store Neo4j

List retrieval uses Neo4j iterator twice (and Neo4j iterator is single-use)

 Description  « Hide
When retrieving elements of a List we traverse the iterator to get the size then do it again to convert the elements. This doesn't work for Neo4j since it returns (broken) single-use iterators that once traversed just return null

SVN trunk fixes this, and also supports JPQL ordered lists ordering clause
