List of nodes taken from org.wildfly.clustering.group.Group is different across nodes ------------------------------------------------------------------------------------- Key: WFLY-5600 URL: https://issues.jboss.org/browse/WFLY-5600 Project: WildFly Issue Type: Bug Components: Clustering, EE, EJB Affects Versions: 9.0.1.Final Environment: Windows 7 64 bit, JDK 1.8_20 64bit Reporter: Piotr Nowicki Assignee: Paul Ferraro Labels: channel, cluster, jgroups Fix For: 10.0.0.Alpha3 I have a cluster of 2 nodes with a WAR application deployed using web-console and exposing EJB remote business interface with following content: {code}@Stateless @Remote public class ServiceImplementation implements Service { @Resource( lookup = "java:jboss/clustering/group/ejb" ) private Group channelGroup; @Override public void printNodeList() { for( Node node : channelGroup.getNodes()) { System.out.println( "node = " + node ); } } } {code} I invoke this EJB from a standalone client multiple times (to make sure that method calls will reach both nodes.) The result is different on both nodes: * On master node the result is *correct* = two nodes' names are printed out , * On second node the result is *incorrect* = *no nodes' names are printed out*. This was working fine in WFLY 8.2.0.Final.
