  <div class="jd-tagdata jd-tagdescr"><p>Invoked when the garbage collector has detected that this instance is no longer reachable.
 The default implementation does nothing, but this method can be overridden to free resources.

 <p>Note that objects that override <code>finalize</code> are significantly more expensive than
 objects that don't. Finalizers may be run a long time after the object is no longer
 reachable, depending on memory pressure, so it's a bad idea to rely on them for cleanup.
