Crash if jdk8 interface with default methods implemented by abstract class.

public interface I {  
    public default void testI() {}
}
public abstract class IA implements I {
}
public class A extends IA {
}
public class B      implements I {
}

I b = new B();
b.testI(); //OK
I a = new A();
a.testI(); //crash

Error:

Yes, I don't think any work has been done to recognize or deal with default methods yet.
