Weak affinity set up by EJB client 4 is not followed with invocations running against stateful bean deploment on WildFly 13 --------------------------------------------------------------------------------------------------------------------------- Key: WFLY-10463 URL: https://issues.jboss.org/browse/WFLY-10463 Project: WildFly Issue Type: Bug Components: Clustering, EJB Affects Versions: 13.0.0.Beta1 Environment: WildFly 13 beta runtimes. EJB client version does not matter (tested with {{org.wildfly:wildfly-ejb-client-bom:12.0.0.Final}}). Reporter: Michal Jurc Assignee: Paul Ferraro Priority: Blocker Fix For: 13.0.0.CR1 Attachments: repro.zip Remote EJB client with {{InitialContext}} setting up weak affinity will not hold up the affinity, resulting in a behaviour that's different to previous releases of WildFly. In previous versions of WildFly, {{java.naming.provider.url}} property of {{InitialContext}} was enough to enforce weak affinity to a node in remote EJB client. This is a regression compared to WildFly 12. The client version does not change the behaviour, which leads me to believe the issue is server-side. Update: The issue affects only stateful bean invocations. {code} while (true) { try { final Properties props = new Properties(); props.put(Context.INITIAL_CONTEXT_FACTORY, WildFlyInitialContextFactory.class.getName()); props.put(Context.PROVIDER_URL, "remote+http://127.0.0.1:8080"); final InitialContext ejbCtx = new InitialContext(props); final HelloBeanRemote bean = (HelloBeanRemote) ejbCtx .lookup("ejb:/server/HelloBean!" + HelloBeanRemote.class.getName() + "?stateful"); for (int i = 0; i < 10; i++) { System.out.println(bean.hello()); } } catch(Exception e) { System.out.println("Call failed!!!!"); e.printStackTrace(); } final Properties props = new Properties(); props.put(Context.INITIAL_CONTEXT_FACTORY, WildFlyInitialContextFactory.class.getName()); props.put(Context.PROVIDER_URL, "remote+http://127.0.0.1:8080"); {code} {code}11:56:02,452 DEBUG [org.jboss.ejb.client.EJBInvocationHandler:164] Calling invoke(module = /server/HelloBean, strong affinity = Cluster "ejb", weak affinity = Node "node1"): node1, 0 11:56:02,460 DEBUG [org.jboss.ejb.client.EJBInvocationHandler:164] Calling invoke(module = /server/HelloBean, strong affinity = Cluster "ejb", weak affinity = Node "node1"): node1, 1 11:56:02,465 DEBUG [org.jboss.ejb.client.EJBInvocationHandler:164] Calling invoke(module = /server/HelloBean, strong affinity = Cluster "ejb", weak affinity = Node "node1"): node1, 2 11:56:02,472 DEBUG [org.jboss.ejb.client.EJBInvocationHandler:164] Calling invoke(module = /server/HelloBean, strong affinity = Cluster "ejb", weak affinity = Node "node1"): node1, 3 11:56:02,477 DEBUG [org.jboss.ejb.client.EJBInvocationHandler:164] Calling invoke(module = /server/HelloBean, strong affinity = Cluster "ejb", weak affinity = Node "node1"): node1, 4 11:56:02,488 DEBUG [org.jboss.ejb.client.EJBInvocationHandler:164] Calling invoke(module = /server/HelloBean, strong affinity = Cluster "ejb", weak affinity = Node "node1"): node1, 5 11:56:02,496 DEBUG [org.jboss.ejb.client.EJBInvocationHandler:164] Calling invoke(module = /server/HelloBean, strong affinity = Cluster "ejb", weak affinity = Node "node1"): node1, 6 11:56:02,502 DEBUG [org.jboss.ejb.client.EJBInvocationHandler:164] Calling invoke(module = /server/HelloBean, strong affinity = Cluster "ejb", weak affinity = Node "node1"): node1, 7 11:56:02,507 DEBUG [org.jboss.ejb.client.EJBInvocationHandler:164] Calling invoke(module = /server/HelloBean, strong affinity = Cluster "ejb", weak affinity = Node "node1"): node1, 8 11:56:02,515 DEBUG [org.jboss.ejb.client.EJBInvocationHandler:164] Calling invoke(module = /server/HelloBean, strong affinity = Cluster "ejb", weak affinity = Node "node1"): node1, 9 11:56:03,535 DEBUG [org.jboss.ejb.client.EJBInvocationHandler:164] Calling invoke(module = /server/HelloBean, strong affinity = Cluster "ejb", weak affinity = Node "node2"): node2, 0 11:56:03,544 DEBUG [org.jboss.ejb.client.EJBInvocationHandler:164] Calling invoke(module = /server/HelloBean, strong affinity = Cluster "ejb", weak affinity = Node "node2"): node2, 1 11:56:03,555 DEBUG [org.jboss.ejb.client.EJBInvocationHandler:164] Calling invoke(module = /server/HelloBean, strong affinity = Cluster "ejb", weak affinity = Node "node2"): node2, 2 11:56:03,561 DEBUG [org.jboss.ejb.client.EJBInvocationHandler:164] Calling invoke(module = /server/HelloBean, strong affinity = Cluster "ejb", weak affinity = Node "node2"): node2, 3 11:56:03,568 DEBUG [org.jboss.ejb.client.EJBInvocationHandler:164] Calling invoke(module = /server/HelloBean, strong affinity = Cluster "ejb", weak affinity = Node "node2"): node2, 4 11:56:03,586 DEBUG [org.jboss.ejb.client.EJBInvocationHandler:164] Calling invoke(module = /server/HelloBean, strong affinity = Cluster "ejb", weak affinity = Node "node2"): node2, 5 11:56:03,595 DEBUG [org.jboss.ejb.client.EJBInvocationHandler:164] Calling invoke(module = /server/HelloBean, strong affinity = Cluster "ejb", weak affinity = Node "node2"): node2, 6 11:56:03,602 DEBUG [org.jboss.ejb.client.EJBInvocationHandler:164] Calling invoke(module = /server/HelloBean, strong affinity = Cluster "ejb", weak affinity = Node "node2"): node2, 7 11:56:03,616 DEBUG [org.jboss.ejb.client.EJBInvocationHandler:164] Calling invoke(module = /server/HelloBean, strong affinity = Cluster "ejb", weak affinity = Node "node2"): node2, 8 11:56:03,628 DEBUG [org.jboss.ejb.client.EJBInvocationHandler:164] Calling invoke(module = /server/HelloBean, strong affinity = Cluster "ejb", weak affinity = Node "node2"): node2, 9 {code}
