/**
* Tests PostRemove callback within a pseudo-container environment.
*
* According to JPA 2.0 Specification Section 3.5.2 (edited for PostRemove only and readability)
*
* "a) The PostRemove callback method is invoked for an entity after the entity has been removed.
*
* b) This callback will also be invoked on all entities to which these operations are cascaded.
*
* c) The PostRemove method will be invoked after the database delete operation. The database operation
* may occur directly after the remove operation have been invoked or they may occur directly after
* a flush operation has occurred (which may be at the end of the transaction)."
* <br>
* The test runs within a test harness that emulates application managed transaction semantics
* of a container.
