[jboss-jira] [JBoss JIRA] (WFLY-10245) Mod_cluster requires Advertise but Multicast interface is not available

Mod_cluster requires Advertise but Multicast interface is not available ----------------------------------------------------------------------- Key: WFLY-10245 URL: https://issues.jboss.org/browse/WFLY-10245 Project: WildFly Issue Type: Bug Components: mod_cluster Affects Versions: 11.0.0.Final Reporter: Bogdan Sikora Assignee: Radoslav Husar Priority: Minor Attachments: standalone-ha.xml, standalone.xml This error message has probably no impact to mod-cluster functionality as tests successfully finished even with this message in workers log. Balancer (standalone.xml) has no error messages. [^standalone-ha.xml] (worker) [^standalone.xml] (balancer) Issue: {noformat} 2016-10-24 03:51:18,393 ERROR [org.wildfly.extension.mod_cluster] (ServerService Thread Pool -- 64) WFLYMODCLS0004: Mod_cluster requires Advertise but Multicast interface is not available {noformat} Environment: Windows machine with Tunnel adapter Teredo Tunneling Pseudo-Interface Scenario: 1. Start Eap (standalone-ha.xml) on Ipv6 address with prefix 2001 (Teredo Tunneling) 2. Look for Mod_cluster Advertising error Error from ContainerEventHandlerService class {code} // Read node to set configuration. if (config.getAdvertise()) { // There should be a socket-binding.... Well no it needs an advertise socket :-( final SocketBinding binding = this.binding.getOptionalValue(); if (binding != null) { config.setAdvertiseSocketAddress(binding.getMulticastSocketAddress()); config.setAdvertiseInterface(binding.getSocketAddress().getAddress()); if (!isMulticastEnabled(bindingManager.getValue().getDefaultInterfaceBinding().getNetworkInterfaces())) { ROOT_LOGGER.multicastInterfaceNotAvailable(); } } } ... private boolean isMulticastEnabled(Collection<NetworkInterface> ifaces) { for (NetworkInterface iface : ifaces) { try { if (iface.isUp() && (iface.supportsMulticast() || iface.isLoopback())) { return true; } } catch (SocketException e) { // Ignore } } return false; } {code}
