Pull Request: 7013: AIX: InetAddress.getByName(addr) does not work as expected

[Thomas Stüfe]

Hi Micheal,

welcome, and thank you for your contribution!

I opened a bug id for you to track this:
https://bugs.openjdk.java.net/browse/JDK-8280498 . I can sponsor this patch
for you.

You need one reviewer, I think. I don't have the cycles right now to think
this through. I cc core-libs dev since this is a networking issue and one
of their tests.

Cheers, Thomas
