I guess this would also be the type of fixing we'd have to apply to each single test.

Thanks, that explains. There's been a flurry of issues related to AIX + multicasting. I think the main issue is that nobody has pointed to something authoritative that says whether AIX allows a dual socket join an IPv4 multicast group or not. It sounds like it doesn't allow it, in which case I assume the issue has been there since JDK 1.4 or whenever the AIX port added support for IPv6.
