You should first make a minimal example that reproduces this. I've just
failed to do so with the following:
abstract class AbstractParent {
public void x() { System.out.println("x"); }
}
public class ConcreteChild extends AbstractParent {
}
user> (set! *warn-on-reflection* true)
true
user> (.x (test.ConcreteChild.))
nil
user> (.x ^test.AbstractParent (test.ConcreteChild.))
nil
user> (def cc (test.ConcreteChild.))
#'user/cc
user> (.x cc)
Reflection warning, NO_SOURCE_PATH:1:1 - reference to field x can't be
resolved.
nil
user>
What must I add to break it?
