File server client returns HTTP 404 for inaccessible files

[adolski]

This is for Restlet 2.3.5 JSE. I set up a simple static file server like this:

public static void main(String[] args) {
    Component component = new Component();
    component.getServers().add(Protocol.HTTP, 8085);
    component.getClients().add(Protocol.FILE);
    component.getDefaultHost().attach("", new WebApplication());
    component.start();
}

class WebApplication extends Application {
    public Restlet createInboundRoot() {
        final Router router = new Router(getContext());
        router.setDefaultMatchingMode(Template.MODE_EQUALS);
        final Directory dir = new Directory(getContext(), "file:///home/me/images");
        dir.setDeeplyAccessible(true);
        dir.setListingAllowed(false);
        dir.setNegotiatingContent(false);
        router.attach("", dir);
        return router;
    }
}

I can now access files located in /home/me/images. But, for inaccessible files (like chmod 000), the server returns an HTTP 404 status code (and prints an IOException with a misleading message), when I would expect it to return 403, like Apache.
