[jboss-jira] [JBoss JIRA] (WFLY-10463) Weak affinity set up by EJB client 4 is not followed with invocations running against stateful bean deploment on WildFly 13

[Paul Ferraro (JIRA)]

     [ https://issues.jboss.org/browse/WFLY-10463?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Paul Ferraro closed WFLY-10463.
-------------------------------
    Resolution: Rejected


After running the reproducer, I don't see anything anomalous with the behavior.  Setting the provider URL allows the client to discover other nodes in the cluster.  The client appropriately load balances SFSB creation to different nodes.  All invocations for a given bean consistently invoke on the same node, as there are no topology changes during the test, so weak affinity is always maintained.

>    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}}).

> 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.
