( I noticed that I accidentally deleted a line in the AIX coding so I brought it back, and I updated the Copyright year info to 2019 ).

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"). See https://www.freebsd.org/cgi/man.cgi?getifaddrs https://developer.apple.com/library/archive/documentation/System/Conceptual/ManPages_iPhoneOS/man3/getifaddrs.3.html Additionally a small resource leak in NetworkInterface.c is fixed.
