   * Test class for PojoCache Enum.
   *
   * @version $Revision: 1.1 $
   *          <p>Below is the annotation that signifies this class is "prepared" under JBossAop. This is used in
   *          conjunction with a special jboss-aop.xml (supplied by JBossCache). In addition, this is JDK1.4 style,
   *          so a annoc Ant build target is needed to pre-compile it.</p>
   *          <p>To use this approach, just apply this line to your pojo and run annoc (and possibly aopc).</p>
