Transaction propagation in asynchronous ejb method call

We have two EJB session beans as given below;

@Stateless
public class MyStatelessSessionBean{
      @EJB
       MyStatefulSessionBean statefulBean;
      public void methodA(){
          statefulBea.methodB();
      }
}

@Stateful
@ TransactionAttribute(TransactionAttributeType.REQUIRED)
public class MyStatefulSessionBean {
     @Asynchronous
     public void methodB(){
     }

}

A client, which is not in any in any transaction, invoke methodA of MyStatelessSessionBean. How many distict transactions will be started by container after all processing has completed ?

There will be 2 transactions started. As EJB 3.1 specification states in point 4.5.3:

Client transaction context does not propagate with an asynchronous method invocation. From the Bean Developer’s view, there is never a transaction context flowing in from the client. This means, for example, that the semantics of the REQUIRED transaction attribute on an asynchronous method are exactly the same as REQUIRES_NEW.
