admin-console fails to load when unexploded EAR containing an EJB module JAR exists in the deploy directory

When an EAP instance has an EAR deployed to it which contains an EJB module JAR and the EAR is in an unexploded form (archived), attempting to access the admin-console results in the following exception:
