Log”_non_loopback_ is deprecated as it picks an arbitrary interface. specify explicit scope(s); interface(s); address(es); or hostname(s) instead” classname is NetworkService.java

                     return NetworkUtils.getFirstNonLoopbackAddresses();
                case "non_loopback:ipv4":
                    logger.warn("_non_loopback_ is deprecated as it picks an arbitrary interface. specify explicit scope(s); interface(s); address(es); or hostname(s) instead");
                    return NetworkUtils.filterIPV4(NetworkUtils.getFirstNonLoopbackAddresses());
                case "non_loopback:ipv6":
                    logger.warn("_non_loopback_ is deprecated as it picks an arbitrary interface. specify explicit scope(s); interface(s); address(es); or hostname(s) instead");
                    return NetworkUtils.filterIPV6(NetworkUtils.getFirstNonLoopbackAddresses());
                default:
                    /* an interface specification */
                    if (host.endsWith(":ipv4")) {
                        host = host.substring(0; host.length() - 5);
