var clientClass = client && service.client.delegatingStubClass;

The clientClass becomes the Connection's localFactory.

I've changed the Connection class to ignore its localFactory parameter if it's
null or undefined. I've removed the '|| function(){}' as suggested.

+    var serviceConnection =
+      new connection.Connection(serviceHandle, clientClass, service.proxyClass);
+    serviceConnection.local.delegate$ = client;
+    serviceConnection.remote.connection$ = serviceConnection;
+    return serviceConnection.remote;
+  }
+
+  var exports = {};
+  exports.connectToService = connectToService;
+  exports.quit = mojo.quit;
+  return exports;
+});
