// all: package demo;
public interface IBar {
void stuff();
}
class Bar {
public void stuff() { System.out.println("stuff"); }
}
class SubBar extends Bar implements IBar {
// implements IBar, via non-public superclass Bar
}
public class Factory {
public static IBar get() { return new SubBar(); }
}Can't invoke from Clojure:

(import '[demo Factory IBar])
(def inst (Factory/get)) ;; instance of SubBar, inferred as IBar
(.stuff inst)
;; IllegalArgumentException Can't call public method of non-public class: public void demo.Bar.stuff() clojure.lang.Reflector.invokeMatchingMethod (Reflector.java:88)Cause: The Reflector is not taking into account that a non-public class can implement an interface, and have a non-public parent class contain an implementation of a method on that interface.
Approach: The solution I took is to pass in the target object's class instead of the declaring class of the method object.
