equality checking instead of object equality.
> This change would still protect against cyclical object graphs, but also protect against
the following conditions:
> * Incorrect implementations of hashCode/equals for any objects in the object graph
> * Unintended side effects of the hashCode/equals methods for any objects in the object
graph
> Unfortunately, Java versions prior to 1.6 do not provide a simple built-in mechanism
to create such a Set.  This issue is discussed here in detail:
> http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4479578
> A possible work-around is to use an IdentityHashMap instead of a Set.  This class is
available in Java 1.4 and later.
