Maybe your systems don't have IPv6 enabled so you never > run into this? Well, in that area we always had deviations on AIX, so definitely this rings a bell. 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. ------------- PR Comment: https://git.openjdk.org/jdk/pull/14142#issuecomment-1586887143
