 /**
  * Abstract class that implements security interception for secure objects.
- * <p/>
+ * <p>
  * The <code>AbstractSecurityInterceptor</code> will ensure the proper startup configuration of the security
  * interceptor. It will also implement the proper handling of secure object invocations, namely:
  * <ol>
  * <li>Obtain the {@link Authentication} object from the {@link SecurityContextHolder}.</li>
- * <p/>
  * <li>Determine if the request relates to a secured or public invocation by ooking up the secure object request
  * against the {@link ObjectDefinitionSource}.</li>
- * <p/>
  * <li>For an invocation that is secured (there is a
  * <code>ConfigAttributeDefinition</code> for the secure object invocation):
- * <p/>
  * <ol type="a">
- * <p/>
  * <li>If either the {@link org.springframework.security.Authentication#isAuthenticated()}
  * returns <code>false</code>, or the {@link #alwaysReauthenticate} is
  * <code>true</code>, authenticate the request against the configured {@link AuthenticationManager}.
  * When authenticated, replace the <code>Authentication</code> object on the
  * <code>SecurityContextHolder</code> with the returned value.</li>
- * <p/>
  * <li>Authorize the request against the configured {@link AccessDecisionManager}.</li>
- * <p/>
  * <li>Perform any run-as replacement via the configured {@link RunAsManager}.</li>
- * <p/>
  * <li>Pass control back to the concrete subclass, which will actually proceed with executing the object.
  * A {@link InterceptorStatusToken} is returned so that after the subclass has finished proceeding with
  * execution of the object, its finally clause can ensure the <code>AbstractSecurityInterceptor</code>
  * is re-called and tidies up correctly.</li>
- * <p/>
  * <li>The concrete subclass will re-call the <code>AbstractSecurityInterceptor</code> via the
  * {@link #afterInvocation(InterceptorStatusToken, Object)} method.</li>
- * <p/>
  * <li>If the <code>RunAsManager</code> replaced the <code>Authentication</code> object, return the
  * <code>SecurityContextHolder</code> to the object that existed after the call to
  * <code>AuthenticationManager</code>.</li>
- * <p/>
  * <li>If an <code>AfterInvocationManager</code> is defined, invoke the
  * invocation manager and allow it to replace the object due to be returned to
  * the caller.</li>
  * </ol>
- * <p/>
  * </li>
- * <p/>
  * <li>For an invocation that is public (there is no <code>ConfigAttributeDefinition</code> for the secure object
  * invocation):
  * <ol type="a">
- * <p/>
  * <li>As described above, the concrete subclass will be returned an <code>InterceptorStatusToken</code> which is
  * subsequently re-presented to the <code>AbstractSecurityInterceptor</code> after the secure object has been executed.
  * The <code>AbstractSecurityInterceptor</code> will take no further action when its
  * {@link #afterInvocation(InterceptorStatusToken, Object)} is called.</li>
  * </ol>
  * </li>
- * <p/>
  * <li>Control again returns to the concrete subclass, along with the <code>Object</code> that should be returned to
  * the caller. The subclass will then return that result or exception to the original caller.</li>
  * </ol>
