EJB 3.x specs Section 4.3.14

The container serializes calls to each stateful and stateless session bean instance. Most containers will support many instances of a session bean executing concurrently; however, each instance sees only a serialized sequence of method calls. Therefore, a stateful or stateless session bean does not have to be coded as reentrant.


Does this mean , below should not work in any app-server (its applicable to stateful as well) ?
other question that is coming to my mind is that in this case , container will create/fetch another instance of MyService bean when save() is invoked. It may or may not be the same instance of MyService bean in when myMethod got invoked by client ? OR it behaves differently depending upon whether the bean is stateful or stateless ?
