final variable not const enough for switch case

I have the following code:

public class Main {

    static final String fu = Week.class.getName();

    public static void main(String[] arg0){

        String h = "dummy";
        switch (h) {
*        case fu:
            System.out.println(8);
            break;
        default:
            break;
        }
    }
}

Now Eclipse complains at * that case expressions must be constant expressions. But I made fu as constant as I know to do! Why is this not enough, what can I do (other than if-else)?
