Calling Replicator#getStatus() on a replicator that hasn't started throws NPE

public class MainActivity extends AppCompatActivity {

    Database db;

    Replicator r;

    URI u;

    @Override

    protected void onCreate (Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);

        DatabaseConfiguration dbc = new DatabaseConfiguration(this);

        try {

            db = new Database("test", dbc);

        } catch (CouchbaseLiteException e) {

            e.printStackTrace();

        }

        try {

            u = new URI("ws://localhost");

        } catch (URISyntaxException e) {

            e.printStackTrace();

        }

        ReplicatorConfiguration rpc = new ReplicatorConfiguration(db, new URLEndpoint(u));

        r = new Replicator(rpc);

        r.getStatus();

    }
