Can automatic module read classes of named module in exported package in Java 9?

Viewed 510

I am trying to see how Weld CDI container can work with JPMS. So I have the following configuration.

I have my named module and weld-se-shaded as automatic module. In my module I have

module my.module {
    requires weld.se.shaded;
    exports com.foo;
}

NewClass

package com.foo;

import javax.enterprise.context.ApplicationScoped;
import javax.inject.Inject;

@ApplicationScoped
public class NewClass {

    @Inject
    private NewBean bean;

    public void doIt() {
        bean.doIt();
    }

}

NewBean class

package com.foo;

import javax.enterprise.context.Dependent;

@Dependent
public class NewBean {

    public void doIt() {
        System.out.println("I am doing it");
    }
}

And this is the result

How to explain this exception

Caused by: java.lang.reflect.InaccessibleObjectException: Unable to make field private com.foo.NewBean com.foo.NewClass.bean accessible: module my.module does not "opens com.foo" to module weld.se.shaded

There is a table here enter image description here from which I can understand that automatic module can read named (application) module. Then why it doesn't?
