> Unknown set types go through a lot of scanning - often involving reflection - before a simple copy constructor is used. These include the commonly used:
> ConcurrentHashMap$KeySet
> ConcurrentHashMap$EntrySet
> FastCopyHashMap$KeySet
> FastCopyHashMap$EntrySet
> Collections$EmptySet
> Collections$SingletonSet
> Collections$EmptyList
> Collections$SingletonList
> Collections$EmptyMap
> Collections$SingletonMap
> these should be treated accordingly to avoid reflection calls.
