Explicitly setting the property in Embedded (as a hack) circumvents the error: System.setProperty("javax.security.jacc.PolicyConfigurationFactory.provider", "org.jboss.security.jacc.JBossPolicyConfigurationFactory"); And yes, I know that's not in a priv block. ;) So what I'm looking for is where in AS we set this property so I can determine why it's not available to me in Embedded.
