"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"

AS workaround, one could register a object factory that returns null:
/subsystem=naming/binding=java\:\/policyRegistration:add(binding-type=object-factory, module=org.jboss.ironjacamar.impl, class=org.jboss.jca.core.naming.NoopJndiStrategy)
