Virtual Extension Method bug report

[Craig P. Motlin]

I've been testing jdk-8-ea-bin-b115-windows-x64-07_nov_2013 and I ran into
a problem. My program compiles and I get an AbstractMethodError when I call
a virtual extension method using the SuperClass.super.method() syntax, when
the method body is defined higher up than SuperClass.

Exception in thread "main" java.lang.AbstractMethodError:
example.EmptyInterface.method()V
at example.ConcreteCallsSuper.method(ConcreteCallsSuper.java:9)
at example.ConcreteCallsSuper.main(ConcreteCallsSuper.java:14)

Here's the code. All three interfaces seem important.

public interface AbstractMethod
{
    void method();
}

public interface VirtualExtensionMethod extends AbstractMethod
{
    @Override
    default void method()
    {
        System.out.println("example.VirtualExtensionMethod.method");
    }
}

public interface EmptyInterface extends VirtualExtensionMethod
{
}

public class ConcreteCallsSuper implements EmptyInterface
{
    @Override
    public void method()
    {
        System.out.println("example.ConcreteCallsSuper.method");
        EmptyInterface.super.method();
    }

    public static void main(String[] args)
    {
        new ConcreteCallsSuper().method();
    }
}
