SC: IncompatibleClassChangeError when calling interface default method from non-public interface

package p;
interface I {
  default void m() {
    System.out.println("works");
  }
}
public abstract class A implements I { // or concrete or implemented in groovy
}

// not in package p
@groovy.transform.CompileStatic // works if CompileDynamic or TypeChecked
class C extends p.A {
  void test() {
    m() // IncompatibleClassChangeError: Found class C, but interface was expected
  }
}
