    [ https://issues.jboss.org/browse/WFLY-6882?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13278055#comment-13278055 ] 

Paul Ferraro commented on WFLY-6882:
------------------------------------

[~wdfink] "Now the expectation is that a client is routed to that server no matter whether this special server is included in the clients initial connection list."
>From where does this expectation come?  The client will only be aware of nodes on which the given bean is deployed.  If the application is a singleton, the topology size will only ever be 1. Thus for a client to be able to connect to a bean deployed as part of a singleton deployment, the client will have to be preconfigured with all possible servers.

> Given that an application contains a SLSB and is clustered, any EJB client will be updated to have a view off all cluster members and is able to use and failover to any node in the cluster no matter whether it is in the initial list of servers.
> Now if the application is marked as "singleton-deployment" via jboss-all.xml and deployed to all servers only one server in a cluster will pick it and make it active.
> Now the expectation is that a client is routed to that server no matter whether this special server is included in the clients initial connection list.
> The interesting thing is that the client.log show that both servers are connected it the application is NOT marked as singleton
> But only the initial server is connected if the app is marked as singleton!
