Hi @jamieletual, I'm currently investigating any possibilities in testing for this change. In the meantime however it could be good to change the title of the PR to "8257235: InetAddress.isReachable should use non-privileged ICMP sockets when available" as it appears to be an Integration blocker (see Integration Blocker section of first PR comment).
