GVM and Proxy for class with module system not fully initialized - gluon

Question

I get following error with my application during startup:
Proxy is not supported until module system is fully initialized
I guess the stack trace won't help much?

What we doe isn't tricky. We simply create a proxy class for an interface. Should we wait for "initialized" or similar before we start the "app"?
Hm... why is the module system unitialized?
Here's a simple example application, based on Eclipse project template:
public class Application extends MobileApplication
{
#Override
public void init()
{
try
{
//Runnable is only an example, the problem occurs with any interface
Proxy.newProxyInstance(getClass().getClassLoader(), new Class<?>[] {Runnable.class}, new InvocationHandler()
{
#Override
public Object invoke(Object proxy, Method method, Object[] args) throws Throwable
{
return null;
}
});
}
catch (Throwable th)
{
th.printStackTrace();
}
addViewFactory(HOME_VIEW, BasicView::new);
}
#Override
public void postInit(Scene scene)
{
Swatch.BLUE.assignTo(scene);
((Stage) scene.getWindow()).getIcons().add(new Image(Application.class.getResourceAsStream("/icon.png")));
}
}
