When running JMS TCK tests, at some point in time, I've got a trace about the JAAS domain being not found:

11:32:58,049 TRACE [org.jboss.security.plugins.mapping.JBossMappingManager] Application Policy not found for domain=java:/jaas/cts.Mapping framework will use the default domain:other

And then subsequent authentication fails:

There are no other org.jboss.security logs before that one.
Previously, a NPE was raised but it was fixed by https://jira.jboss.org/jira/browse/SECURITY-484.
Still, the root issue is that somehow the AS does not find the Application policy for the domain for some reasons.

The only hint I have is that happens when running the tests for a long period of time (1h or more). If I restart the AS server and run the failing tests, they all pass.
