Description
In NetworkInterface.c and Inet6AddressImpl.c we have some coding that omits checking for ifa_addr == NULL when iterating on the result of the getifaddrs call. This is similar to what has been fixed in hotspot with
https://bugs.openjdk.java.net/browse/JDK-8208676
The issues are in the bsd/macOS coding. However bsd/macOS also document that ifa_addr can be NULL in special cases (not sure how likely it is to see it "in the wild").
