so on windows 10 with native-image: 

(ns script
  (:gen-class))

(defn -main [& args]
  (println (slurp *in*)))
yields a stacktrace involving jni and java.io.FileInputStream.readBytes, but: 
(ns script
  (:gen-class))

(defn -main [& args]
  (println (slurp (clojure.lang.LineNumberingPushbackReader. (java.io.InputStreamReader. System/in)))))
doesn't (and produces the expected output). the testing is from powershell and cmd.exe, with something like: type project.clj | .\my-native-image.exe i think it works fine for linux distributions and macos.

the difference that stands out here is that in is dynamic, while the second example lacks that.
