Java over-engineered?

The following gem, that belongs into a Java programming best practices book, was found in the source of Sun's JDK.

public class StubFactoryFactoryProxyImpl extends StubFactoryFactoryDynamicBase
{
    public PresentationManager.StubFactory makeDynamicStubFactory(
        PresentationManager pm, PresentationManager.ClassData classData,
        ClassLoader classLoader )
    {
        return new StubFactoryProxyImpl( classData, classLoader ) ;
    }
}

Well, I must confess this is almost better than the simple Hello World in Java [cached copy].
