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

[Radoslav Husar (JIRA)]

    [ https://issues.jboss.org/browse/WFLY-10463?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13582833#comment-13582833 ] 

Radoslav Husar commented on WFLY-10463:
---------------------------------------

This issue seems to me like misunderstanding of affinity. Affinity pertains to the proxy, not the client. Thus {{Context.PROVIDER_URL}} (1) has nothing to do with enforcing affinity (though in many cases it will be the same node, e.g. single node deployment). The API to set weak affinity is {{org.jboss.ejb.client.EJBClient#setWeakAffinity}}.

Regardless of that, if any of this turns out to be a bug, certainly not a blocker.

>         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.
