问如何在java8中将方法的可见性/可访问性限制到子包？

EN

package abc;

import java.util.function.Consumer;

import abc.def.B;
import java.lang.Objects;

public class A {
    public static Consumer<A> getPrintAccess(B.AccessToken token) {
        Objects.requireNonNull(token);
        return A::print;
    }

    private void print() {
        System.out.println("privileged action");
    }
}

package abc.def;

import abc.A;

public class B {
    public static class AccessToken {
        /* non-public */ AccessToken() {}
    }

    void someMethod(A object) {
        A.getPrintAccess(new AccessToken()).accept(object);
    }
}
