Security-realms with jaas authentication methods fail to load login-modules from org.jboss.* module in JBoss EAP 6 and 7

Issue

• Why do security-realms that defer to jaas fail to load login-modules from org.jboss.as.security or org.jboss.security.negotiation module in JBoss EAP 7?
• login-module configuration is not working with AdvancedLdapLoginModule.
• The ManagementRealm is configured to defer to JAAS (e.g. <jaas name="example-jaas-domain"/>) and that security-domain is configured to use a login module from the org.jboss.as.security module (i.e. RealmDirect, RealmUsersRoles, Remoting):

                <security-domain name="example-jaas-domain" cache-type="default">
                    <authentication>
                        <login-module code="RealmUsersRoles" flag="required">
                            <module-option name="rolesProperties" value="file://${jboss.server.config.dir}/roles.properties"/>
                            <module-option name="usersProperties" value="file://${jboss.server.config.dir}/users.properties"/>
                        </login-module>
                    </authentication>
                </security-domain>

This results in the following error message:
