Explicitly calling a default method in Java

by

Java 8 introduces default methods to provide the ability to extend interfaces without the need to modify existing implementations.

I wonder if it’s possible to explicitly invoke the default implementation of a method when that method has been overridden or is not available because of conflicting default implementations in different interfaces.

interface A {
    default void foo() {
        System.out.println("A.foo");
    }
}

class B implements A {
    @Override
    public void foo() {
        System.out.println("B.foo");
    }
    public void afoo() {
        // how to invoke A.foo() here?
    }
}

Considering the code above, how would you call A.foo() from a method of class B?
