/**
 * Full-fledged default implementation of the SessionFactory interface:
 * creates ClientSessions for a given ServerSession.
 *
 * <p>Can create a special ClientSession subclass for managed Sessions, carrying
 * an active UnitOfWork that expects to be committed at transaction completion
 * (just like a plain TopLink Session does within a JTA transaction).
 *
 * <p>Can also create a transaction-aware Session reference that returns the
 * active transactional Session on <code>getActiveSession.
