Unable to deploy exploded EJB within an exploded EAR if EJB directory is deeper than below the EAR directory

We have an EAR structured like the following:

It is actually a simple exploded EAR with a single session EJB from the EJB3 tutorial.

The EJB will not deploy.

sample.ear
ejbs
ejbclasses.jar
META-INF
application.xml

The only error is the following:

DEPLOYMENTS MISSING DEPENDENCIES:
Deployment "jboss.ejb3:application=simple,module=ejbclasses,component=CalculatorBean,service=EjbEncFactory" is missing the following dependencies:
Dependency "jboss.naming:application=simple,component=CalculatorBean,module=ejbclasses" (should be in state "Installed", but is actually in state "** NOT FOUND Depends on 'jboss.naming:application=simple,component=CalculatorBean,module=ejbclasses' **")
Deployment "jboss.j2ee:ear=simple.ear,jar=ejbclasses.jar,name=CalculatorBean,service=EJB3" is missing the following dependencies:
Dependency "jboss.ejb3:application=simple,component=CalculatorBean,module=ejbclasses,service=EjbEncFactory" (should be in state "Installed", but is actually in state "Described")

Dependency "jboss.j2ee:ear=simple.ear,jar=ejbclasses.jar,name=CalculatorBean,service=EJB3" (should be in state "Installed", but is actually in state "Instantiated")

NOTE the module name shown for jboss-switchboard. It is ejbs/ejbclasses and in the dependency errors it is only known as ejbclasses?

If I change the structure to the following the EJB will deploy:

sample.ear
ejbclasses.jar
META-INF
application.xml
