Hi Chris, I had already created a bug report for this: https://bugs.openjdk.java.net/browse/JDK-8158170 in the meanwhile but unfortunately, by mistake, I had just sent this information to Doychin and not to the mailing list. So, feel free to close and mark my bug as duplicate.
I also started work on testing Doychin's approach but did not yet find time to finish it - so you overtook me on that one also. As for AIX, there is no getifaddrs available. So there we have to stick to the ioctl approach. I'll take a deeper look next week.
