Hi, I wasn't able to run the test yet; need to find a machine where I could run this test without worrying about restoring it to a working state.
However, looking at the code, I think it's broken already. JDK-8046500 says GetIpAddrTable fails on IPv6-only machines. This method is only called in `lookupIPAddrTable`, and `getAllInterfacesAndAddresses` ignores -2 result since 7f1f9a50ae87e745e552ed8a3b7028cd49638441.
Still, `enumAddresses_win` probably needs more love. I'll look into it.
