With 1.2:
(set! *warn-on-reflection* true)
(time (amap an-array idx ret (+ (int 1) (aget an-array idx
Reflection warning, NO_SOURCE_PATH:52 - call to aclone can't be resolved.
Reflection warning, NO_SOURCE_PATH:52 - call to alength can't be resolved.
Reflection warning, NO_SOURCE_PATH:52 -
It's slow because it has to use reflection to determine the type.
Use (set! *warn-on-reflection* true) and you'll see the warning.
Try something like this and you'll see significantly faster results:
(let [#^testType t (new testType 1 2 3)]
(time (dotimes [_ 1000] (.a t)))

(defn rotate [n s]
(let [[front back] (split-at (mod n (count s)) s)]
(concat back front)))
Don't forget (mod n 0) is an ArithmeticException.
