I haven't read JICP that you refer to, but I believe that they are effectively immutable.
See a post by me in this thread titled "Clojure Concurrency and Custom Types" from March 2013 for how to stay within Clojure, but I believe requiring Java interop calls, to mutate in place Clojure's immutable data structures: https://mail.google.com/mail/u/0/#search/label%3Aclojure+concurrency+and+custom+types/13d9d40bc9dd658a I have never seen code like that in any Clojure libraries I have looked at, though.
