setting <jacc-star-role-allow> in jboss-web.xml does not set allRolesMode to "authOnly"

I am trying to get only authentication (no authorization) to work for web application.

In EAP 5, all that was required was to set the <role-name> to a '*' in
the <security-constraint> of the web.xml. I tried this in EAP 6,
however, it did not work.

I then found the <jacc-star-role-allow> setting that goes in the
jboss-web.xml. Unfortunately, adding this option did not cause the
wildcard ('*') role-name to work for allowing any authenticated user
to access the web application.

Using the following system property does appear to work:
org.apache.catalina.realm.RealmBase.ALL_ROLES_MODE=authOnly

How reproducible:
Everytime.

Steps to Reproduce:
1. Set <role-name>*</role-name> in the security-contraint
2. Set <jacc-star-role-allow>true</jacc-star-role-allow> in jboss-web.xml
3. Set the security-domain so that no roles are assigned to a user
4. Attempt to access the web app

Actual results:
403 - access denied

Expected results:
200 - access allowed
