PersistenceStore
The persistence store allows access to the persistent
storage mechanism within the application.
PersistenceStore instances ARE NOT
thread safe. The best practices approach for using
the persistence store is to use
PersistenceStoreContainer.getStoreForThread()
any time the store is to be accessed.
