Consider the following two classes.

package jdk.jfr.internal;
public class Control {
}

package jdk.jfr;
public class SettingControl extends Control {
}

Control is an internal class in a package that is not exported and SettingControl is an exported class in a public API. Today the generated Javadoc for the SettingControl class contains the following class hierarchy.

     java.lang.Object
        jdk.jfr.internal.Control
            jdk.jfr.SettingControl

It would be good if jdk.jfr.internal.Control was hidden, as it would be if jdk.jfr.internal.Control was a package private class in jdk.jfr.
