"NameNotFoundException due to policyRegistration – service jboss.naming.context.java.policyRegistration" is recorded in server.log during quickstart example run by changing log level:
<logger category="org.jboss.as.security">
<level name="TRACE"/>
</logger>
<logger category="org.jboss.security">
<level name="TRACE"/>
</logger>
See detailed description in community discussion #907134
I choose Jira component picketbox since the exception is titled as "PBOX000293: Exception caught: javax.naming.NameNotFoundException"

To reproduce:
run ejb-security example with trace log level for "org.jboss.secuirty" and "org.jboss.as.security". Then login from page: localhost:8080/wildfly-ejb-security with username and password. The result is successful, however, you will see the exception in server.log file.
