On page 43, in the comment inside code example:

<source lang="java">
import java.awt.*;
import java.util.*;
/** Could be compiled on JDK 1.2, before java.util.List was created */
public class VList extends List {
Vector v;
}
</source>

[[Yoshiki]] thinks, "JDK 1.2" should read "JDK 1.1". True. Looking at {{JDK|java/util|List}}
one can see "since 1.2". As such the comment should say JDK 1.1. The online online sources are fixed:
