      A simple project is attached, which demonstrates the problem:
      deploy the jar file to Wildfly - the server.log will print some lines, which show, that the calls to to TestReader EJB from the created threads are not executed before the @PostConstruct Thread has finished.

      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.
