Principal from @RunAsPrincipal bean annotation does not get authorised with role from @RunAs bean annotation unless the user exists in backing security realm

1. Add Elytron application security domain to EJB subsystem: /subsystem=ejb3/application-security-domain=other:add(security-domain=ApplicationDomain) 2. Attempt to deploy the bean deployment to server: deploy /path/to/startup-runas-beans.jar The following error is produced: 10:14:25,221 ERROR [org.jboss.as.server] (management-handler-thread - 1) WFLYSRV0021: Deploy of deployment "startup-runas-beans.jar" was rolled back with the following failure message: { "WFLYCTL0080: Failed services" => { "jboss.deployment.unit.\" startup-runas-beans.jar\ ".component.SingletonStartupBean.START" => "org.jboss.msc.service.StartException in service jboss.deployment.unit.\" startup-runas-beans.jar\".component.SingletonStartupBean.START: java.lang.IllegalStateException: WFLYEE0042: Failed to construct component instance Caused by: java.lang.IllegalStateException: WFLYEE0042: Failed to construct component instance Caused by: org.wildfly.security.authz.AuthorizationFailureException: ELY01088: Attempting to run as \ "testuser\" authorization operation failed"}, "WFLYCTL0412: Required services that are not installed:" => [ "jboss.deployment.unit.\" startup-runas-beans.jar\ ".component.SingletonStartupBean.START" ] } 3. Add the testuser user to application-users.properties that the default Elytron ApplicationRealm uses with any password and deploy again. The deployment will work, and the SingletonStartupBean 's @RunAs and @RunAsPrincipal will be both correctly set as SingletonStartupBean.init method will invoke StatelessBean.getCallerPrincipal method and log a concise message with the principal: 10:53:29,800 INFO [mock.ejb.SingletonStartupBean] (ServerService Thread Pool -- 74) =================================================== 10:53:29,801 INFO [mock.ejb.SingletonStartupBean] (ServerService Thread Pool -- 74) SingletonStartupBean invoked StatelessBean with principal testuser 10:53:29,801 INFO [mock.ejb.SingletonStartupBean] (ServerService Thread Pool -- 74) ===================================================
