if the stateless session bean instance has an ejbCreate method, the container should treat the ejbCreate method as the instance's PostConstruct method

4.3.10.2 If the stateless session bean instance has an ejbCreate method,
the container treats the ejbCreate method as the instance's PostConstruct method,
and, in this case, the PostConstruct annotation (or deployment descriptor metadata)
can only be applied to the bean's ejbCreate method.
