How to get annotations of Kotlin property from Java?

I have a kotlin class whose properties have a Java annotation, but i can't acess these annotations with Java reflection:

class TestClass(@A var field : String)

The following test prints null:

public class TestKotlinField {

    @Retention(RetentionPolicy.RUNTIME)
    public @interface A{}

    @Test
    public void test() throws NoSuchFieldException {
        System.out.println(TestClass.class.getDeclaredField("field").getAnnotation(A.class));
    }
}

How can i get the annotations of a given kotlin property?
