Support should be in WildFly Elytron, the majority of the code presently lives within WildFly Core.

However to complicate it further the current implementation presently depends upon "java.security.acl.Group" - we probably should skip this step if the Group interface is not available.

We may be able to do a better multi release jar switch later but I think that will depend upon the project moving to be built with Java 17.
