It happens from time to time that someone mistakenly inserts an import
statement between the class comment and the class declaration,
with the result that no class comment is generated.

People get baffled by this (and in large documents, I'll bet
they don't always notice the comments are missing). Could
javadoc please emit a warning in this case.

/**
 * This is the class comment
 * @author Biz
 * @version 04/02/2001
 */

import java.io.*;

public class MyClass {
}
