on server shutdown excessive ERROR logs are produced related to EJB invocations on beans in state shutdown.

2014-04-26 09:38:43,059 ERROR [org.jboss.as.ejb3.invocation] (ServerService Thread Pool – 377) JBAS014134: EJB Invocation failed on component SMSQueueConsumer for method public void at.telekom.sms.esms.service.
common.queue.SMSQueueConsumer.stopping(): org.jboss.as.ejb3.component.EJBComponentUnavailableException: JBAS014559: Invocation cannot proceed as component is shutting down
at org.jboss.as.ejb3.component.interceptors.ShutDownInterceptorFactory$1.processInvocation(ShutDownInterceptorFactory.java:59) [wildfly-ejb3-8.0.0.Final.jar:8.0.0.Final]
at org.jboss.invocation.InterceptorContext.proceed(InterceptorContext.java:309)

IMHO this is definitely no error and is very alarming for production environments, INFO w/o stacktrace, in level DEBUG full stacktrace would suffice.
