I ran into a hang running the org.jboss.as.testsuite.integration.ejb.injection.ejb.EjbInjectionSameEjbNameTestCase test in AS7.

After taking a thread dump it appears that a service is not coming up even though all it's dependencies are availible.

Due to the nature of this test the service and it's dependants are being installed by different threads, possibly at the same time.
