JBossStandaloneEJBContainerProvider does not respect javax.ejb.embeddable.provider property as required by EJB 3.1 specification:

22.3.3

...

The EJBContainer bootstrap class will locate all of the container providers by their provider config-
uration files and call EJBContainerProvider.createEJBContainer(Map<?, ?>) on
them in turn until an appropriate backing provider returns an EJBContainer. A provider may deem
itself as appropriate for the embeddable application if any of the following are true :
• The javax.ejb.embeddable.provider property was included in the Map passed to
createEJBContainer and the value of the property is the provider’s implementation
class.
• No javax.ejb.embeddable.provider property was specified.
If a provider does not qualify as the provider for the embeddable application, it must return null when
createEJBContainer is invoked on it.

...


JBossStandaloneEJBContainerProvider implementation always try to instantiate a container regardles of No javax.ejb.embeddable.provider property setting.

This violates EJB specs and makes TCK6 test com/sun/ts/tests/ejb30/lite/packaging/embed/provider/Client.java to pass by pure luck or to fail on JDK8.
