Immutables should be optimised for more set implementations
-----------------------------------------------------------

                 Key: JBCACHE-1535
                 URL: https://jira.jboss.org/jira/browse/JBCACHE-1535
             Project: JBoss Cache
          Issue Type: Feature Request
      Security Level: Public (Everyone can see)
    Affects Versions: 3.2.0.GA
            Reporter: Manik Surtani
            Assignee: Manik Surtani
             Fix For: 3.3.0.GA


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.
