Embedded doesn't open Google

Hi

I have a strange behavior of the embedded component. I try to open a new sub-window with an embedded component, which should show a URL.
This are my method.

private void showURL(){
	final Window win = new Window();
        win.setCaption("URL");
        win.setModal(true);
        win.setResizable(true);
        win.setDraggable(true);
        win.setHeight("570px");
        win.setWidth("725px");

        VerticalLayout vl_url = new VerticalLayout();
        vl_url.setWidth("100%");
        vl_url.setHeight("450px");
        
        Embedded emb = new Embedded();
        emb.setType(Embedded.TYPE_BROWSER);
		emb.setSizeFull();
		vl_url.addComponent(emb);
		emb.setSource(new ExternalResource("http://www.google.com"));
        
        win.addComponent(vl_url);
        
        getWindow().addWindow(win);
}

If i set the external resource e.g. to http://www.yahoo.com or anything else, that works. But the Google page doesn’t open.
Any idea why this happens?

I would say that Google doesn’t want you to embed Google search into iframe so Google’s somehow blocking it.
