 * <B>Keywords:</B> persistencemanagerfactory <br>

 * JDOUserException after the PersistenceManagerFactory is closed. The exception contains an array
 * of nested exceptions; each nested exception contains as its failed object the PersistenceManager
 * whose Transaction is still active. During close of the PersistenceManagerFactory, all
 * PersistenceManager instances obtained from this PersistenceManagerFactory are themselves closed.
