`Menu.java` and `MenuItem.java` have *Accessibility support* sections where `AccessibleAWTMenu` and `AccessibleAWTMenuItem` classes are defined.

https://github.com/openjdk/jdk/blob/2f7c65ec48dc35d75eed8af411d482ba40de70dc/src/java.desktop/share/classes/java/awt/Menu.java#L618-L628

Thus AWT components implement the same accessibility interfaces that Swing components do. JAWS uses these interfaces. Mystery solved.
