Again, (Boolean. false) is an object. Objects returned from Java are values from Clojure's perspective like numbers, ....
Clojure is a Lisp but allows you to access Java's object world. It's not because the object wraps a property containing a boolean primitive value that it should behave the same as Clojure's boolean type. Other classes may wrap a primitive boolean value in a property and you would not like these to be converted to a Clojure boolean value, you would like to retain a handle on the object. Why should Boolean objects be different ? They are a Java creation, they have nothing to do with the type value system of Clojure.
