index.html 404 page not found

I am facing a weird problem. Indeed I can't have the index.html to work. I have the Application controller in app.controllers and the index.html in app/views/Application/index.html.

The application controller is with just:
public static void index() {
        render();
}

and in the routes, I have:
GET / Application.index.

It is actually the default I get after I ran play run myApp.

If I add my own route, for example:
GET /subscribe.html UserController.subscribe

And I create this UserController with the method subscribe, it works. Is there a problem with the index in the 1.0-stable3 ?
