However, since AIX was not the most important platform for us and that particular IPv6/IPv4 multicast feature didn't seem to be mission critical and wouldn't fail TCK tests, we rather resorted to excluding some tests internally, I believe. But it would be good to really resolve this compatibility/spec/documentation issue, if possible.

The spec doesn't require that a DatgaramSocket or DatagramChannel to an IPv6 socket be capable of joining an IPv4 multicast group. So the tests in several areas might need updates as I don't think we've had a platform to date where it wasn't possible.

@AlanBateman , is it possible if there is a central place where the change could me made for fixing all of the multicast  test cases?
