Methods without Security Domain but with RolesAllowed, PermitAll, DenyAll, RunAs, RunAsPrincipal default to security domain other in JBoss EAP 6.1

Issue

• We have not enabled any security at individual EJB or method level. What is recommendation, because we came across JBOSS 7.2.X article (like Securing EJBs) that claims that

"Starting, JBoss AS 7.2.x, the presence of any security metadata (like @RolesAllowed, @PermitAll, @DenyAll, @RunAs, @RunAsPrincipal) on the bean or any business method of the bean, makes the bean secure, even in the absence of an explicitly configured security domain. In such cases, the security domain name is default to "other". Users can explicitly configure an security domain for the bean if they want to using either the annotation or deployment descriptor approach explained earlier."
