why no dominance here?

Code: Select all

Object obj = 10;
        final int a = 50;
        switch(obj){
            case Integer d when a==a : {
                System.out.println("Integer "+d);
                break;
            }
            case Double d when a==a : {
                System.out.println("Double "+d);
                break;
            }
            default : System.out.println("Object "+obj);
        }

Note sure which one you think dominates the other here? Integer and Double have no parent/child relation.
