Description

When a web application contains both MBean (jboss-service.xml) and persistence-unit (persistence.xml), the WAR deployment fails due to the following NullPointerException:

}

This NPE happens because WebNonTxEmCloserAction#dependencies() returns null. It should return Collections.emptySet() instead of null.
