org.datanucleus.store.rdbms.table.PersistableJoinTable
Representation of a join table for the case where we have an N-1 unidirectional relation stored in a join table. It's a minority interest situation, but worth inclusion. The "owner" in this case is the side with the relation (the "N" side). The "related" is the other side.

                join = new ArrayTable(tableName, mmd, RDBMSStoreManager.this);
            }
            else if (type == JOIN_TABLE_PERSISTABLE)
            {
                join = new PersistableJoinTable(tableName, mmd, RDBMSStoreManager.this);
