@RunAs role in org.jboss.jsr299.tck.tests.event.observer.transactional.TransactionalObserversTest

org.jboss.jsr299.tck.tests.event.observer.transactional.TransactionalObserversTest failed to deploy on glassfish server due to no security role mapping for @RunAs roles defined in EJB classes. By creating a default mapping in glassfish through sun-ejb-jar.xml, the test was able to deploy/run. But we were wondering about the intention of the @RunAs role as the tests do not seem to actually use the security constraints.

And when this test ran in JBoss environment, how is the security role mapping done for these @RunAs roles?
