The following might point into the direction you need.
;; simple function to get a fresh classloader
(defn make-fresh-classloader [] (proxy [java.lang.ClassLoader] []))
;; Global var, since we want something bindable
(def *my-classloader*)
;; Use a fresh classloader in a binding-form
(binding [*my-classloader* (make-fresh-classloader)]
(comment Your code, in which the classes you want to be
disposed later should be loaded via the fresh
classloader,
not via the system classloader))
Assuming you leak neither newly allocated Class-objects nor instances
thereof outside the binding-block, the created classloader will be GCd
(along with classes loaded by it) sometime after the binding-block has
been executed (allocated Classe-objects retain a reference to their
classloader, so leaking them would prevent the classloader from being
GCd).
