Richard Achmatowicz commented on WFLY-13132:
--------------------------------------------
In order to permit the specification of multiple connectors to the <remote/> element, I am replacing the attribute connector-ref (as in <remote connector-ref="connector-name"/>) with a list of connector names <remote connectors="<list of connector names>"/>, so that a single or multiple connector references can be passed to the remote connector. So the current issue can be fixed by defining <remote connectors="remoting-connector http-remoting-connector"/>
The now legacy attribute connector-ref will be deprecated.
Transformers need to be set up to transform new configurations for the <remote/> element to legacy configurations of the remote element. The initial attempt at this will be as follows:
* connectors
** undefined -> discard attribute
** defined and list size == 1, convert to connector-ref attribute using that list element
** defined and list size > 1, reject attribute as no legacy configuration can handle two connectors
* connector-ref
** undefined - > discard attribute
** defined and connectors is undefined -> pass attribute through with message that connector-ref is deprecated
** defined and connectors is defined -> reject with message that connector-ref and connectors cannot both be defined and connector-ref is deprecated

> h2. +Conclusion+
> Depending on what is configured as {{connector-ref}} in the {{remote}} of the _ejb3_ subsystem the {{CLUSTER_TOPOLOGY}} update is different. From a client perspective it would be expected that either the {{CLUSTER_TOPOLOGY}} update would _only_ contain destinations that are applicable for the _connector/protocol_ that has been used, or maybe even _ALL_ available destinations, as the client could potentially run a mix of protocols between invocations...
