Why can’t static methods be abstract in Java?

The question is in Java why can’t I define an abstract static method? for example

abstract class foo {
    abstract void bar( ); // <-- this is ok
    abstract static void bar2(); //<-- this isn't why?
}

Poor language design. It would be much more effective to call directly a static abstract method than creating an instance just for using that abstract method. Especially true when using an abstract class as a workaround for enum inability to extend, which is another poor design example. Hope they solve those limitations in a next release.
