 * production application, it is highly recommended that the internal User {@link #getRoles} collection be cached
 * in a 2nd-level cache when using JPA and/or Hibernate.  The hibernate xml configuration for this sample application
 * does in fact do this for your reference (see User.hbm.xml - the 'roles' declaration).</p>
