The compiler fails to reject this program:

import java.lang.annotation.Annotation;
import java.lang.reflect.Constructor;
public class X {
  void bar(Constructor constructor, Class<Ann> ann) {
    constructor.getAnnotation(ann).message(); // Should fail
  }
}
@interface Ann {
  String message();
}

class Y {
  void bar(MyConstructor constructor, Class<Ann> ann) {
    constructor.getAnnotation(ann).message(); // Should fail
  }
}

interface Z {
  <T extends Annotation> T getAnnotation(Class<T> c);
}
class MyAccessibleObject implements Z {
  public <T extends Annotation> T getAnnotation(Class<T> c) { return null; }
}
class MyConstructor<V> extends MyAccessibleObject {
  public <T extends Annotation> T getAnnotation(Class<T> c) { return null; }
}
