Rajesh P commented on OAK-3470:
-------------------------------

your RDBDocumentStore is not initialized. if you change your code to below then it works : 

JdbcDataSource ds = new JdbcDataSource();
        ds.setURL("jdbc:h2:tcp://localhost/~/oak;DB_CLOSE_DELAY=-1");
        ds.setUser("sa");
        ds.setPassword("sa");

        // Build the OAK Repository Instance
        RDBDocumentStore rdbDocumentStore=null;
        try {
            DocumentMK.Builder builder = new DocumentMK.Builder();

            // Build the OAK Repository Instance
            rdbDocumentStore = new RDBDocumentStore(ds,builder);

        } finally {
            if (rdbDocumentStore != null) {
                rdbDocumentStore.dispose();
            }
        }
