I think I have found a solution for a bug JDK-8071693.
The problem is the Introspector does scan only in super classes and does not
know about default methods.
I just added condition method.isDefault() and manual testing proves my idea
does work. I did NOT run junit tests.
Can you please review this patch in attachment?
