------------------------------------------------------------------

EJB spec 4.8.1 does not apply to this bug, please re-investigate.
Singleton bean A (=ServerImpl) with @startup calls in its @Postconstruct method a method in singleton bean B (=TestReaderImpl)  - this works fine.

Now in this @PostConstruct several Threads are created with a ManagedExcecutorService - these threads start normally, but if they call a method iin singleton bean B, they are blocked. This must not happen and is a bug.

> Wildfly 8.2.0 and 10.0.0 work fine with a Singleton Bean, which has a @Postconstruct method and in this method several threads are created with the ManagedExecutorService. These  threads call a method in another Singleton EJB, which has been injected.
> This call is blocked in Wildfly 10.1.0 until the Prostconstruct thread has ended.
> I assume that the behaviour of Wildfly 8.2.0 + 10.0.0 is correct and the behaviour of Wildfly 10.1.0 is a bug.
