Yes, the error is there. I also created a *lein new app* project, which by
default creates a gen-classed main namespace:
(ns call-test.core (:gen-class))
(set! *warn-on-reflection* true)
(defn -main [& args] (.x (test.ConcreteChild.)))
Now try *lein do clean, uberjar. *It will report a reflection warning while
AOT-compiling.
Then do *java -jar target/call-test-0.1.0-SNAPSHOT-standalone.jar *and see
it fail.
This cleanly separates compile time from runtime.
