/**
* Test JPA 2.0 section 7.6.2.1
* <p>
* Inheritance of Extended Persistence Context
* <p>
* "
* If a stateful session bean instantiates a stateful session bean (executing in the same EJB container instance)
* which also has such an extended persistence context, the extended persistence context of the first stateful
* session bean is inherited by the second stateful session bean and bound to it, and this rule recursively
* applies—independently of whether transactions are active or not at the point of the creation of the stateful
* session beans.
* "
* <p>
* This tests the "shallow" inheritance where the above only applies to parent/child relationships (not recursively
* up and vertically which is "deep" inheritance).
