HostControllerRegistrationHandler has logic for determining if a secondary HC is running JBoss AS 7.1.1. (Not EAP 7.1; AS 7.1.1 which preceded EAP 6.0!!!) Look for variable 'as711'.

It rejects the secondary host registration if that is the release. Consider updating this to reject kernel API versions prior to WF 23.

Note: I repurposed this JIRA from what it was originally about (which was removing this logic and hopefully a lot more. I don't think it makes sense to remove this logic as it's just a few LOC and has a valid purpose. And the "a lot more" I was thinking about isn't really related to this logic.
