In this case there is no need for mutable primitives.
You can try a direct translation of your java code:
(let [n (alength w)]
(loop [doc (int -1) i (int 0)]
(when (< i n)
(let [new-doc (aget d i)
(when-not (= doc new-doc)
(load doc))
(when-not (malformed doc)
(process new-doc (aget w i))
(recur new-doc (inc i)))))))
You can tweeak it here and there (== and unchecked-inc for example) and
don't forget to typehint d and w if Clojure doesn't infer their type.
