Nullpointerexception with Google Maps Addon

Hi there,

I am getting this Exception on first call.
The setup is really simple, so I don't get the problem.

Setup:

Eclipse 3.7.2
Vaadin 6.7.7
GMaps Addon 0.9.13

public class VaadinApplication extends Application {
@Override
public void init() {
Window mainWindow = new Window("Vaadin Application");
setMainWindow(mainWindow);
GoogleMap googleMap_1 = new GoogleMap(this, new Point2D.Double(22.3, 60.4522), 8);
googleMap_1.setImmediate(false);
googleMap_1.setWidth("220px");
googleMap_1.setHeight("313px");
googleMap_1.addMarker(new BasicMarker(1L, new Point2D.Double(22.3, 60.4522), "Test marker"));
mainWindow.addComponent(googleMap_1);
}
}

Exception on first call:
