>From https://docs.oracle.com/javase/8/docs/technotes/guides/net/ipv6_guide/: "f a socket is bound to an IPv6 anylocal address on a dual-stack machine, it can accept both IPv6 and IPv4 traffic; if it is bound to an IPv4 (IPv4-mapped) anylocal address, it can only accept IPv4 traffic". Seems that the scenario you have is not supported by the JDK. -- Simone Bordet ---- http://cometd.org http://webtide.com Developer advice, training, services and support from the Jetty & CometD experts. _______________________________________________ jetty-users mailing list jetty-users@eclipse.org To unsubscribe from this list, visit https://www.eclipse.org/mailman/listinfo/jetty-users
