Eclipse Ant Javadoc - warning of no comment on private field

Question

Running the Ant Javadoc process in Eclipse (2022-09 (4.25.0)) with <javadoc access="public"

Getting a handful of these warnings on private fields. However, there are many private fields that it does not complain about.

 [javadoc] D:\workspace_12\...\NetConfCredential.java:47: warning: no comment
 [javadoc]  private boolean verified = false;

It should be ignoring all private fields, no? It does not complain about all of the private methods that do not have javadoc.

===================== While minimizing the code to post an example, I found that it has to do with java.io.Serializable.

public abstract class TestAbstract implements java.io.Serializable
{
        /** Our serialization ID */
    public static final long serialVersionUID = 12;
}

/**
 * Comment.
 */
public class TestCredential extends TestAbstract
{
        /** UID */
    public static final long serialVersionUID = 12;

    private static final String defaultString = "public";

    private boolean verified = false;

    /**
    * Constructor
    */
    public TestCredential() {   }
}

 [javadoc] D:\workspace_12\...\TestCredential.java:13: warning: no comment
 [javadoc]  private boolean verified = false;
 [javadoc]  

            ^

Remove Serializable from the superclass and the warning goes away. Javadoc does not warn about the private static field.
