I was asked to post my question here.

Later, rereading the chapter helped me understand it a little more, so i sent
another one:

me and my bad habit...
re-reading the whole chapter a couple of times i can say that my question was
way way off.
Since the classes presented in the book override the repaint() method of a
JComponent,
and the code of the override doesnt call upate(), my question was not valid.
(Though a hint printed in discrete font at the end of the page stating that fact
could hava saved me some time)

Thats what happens when you lack intelligence while having the bad habit of
trying to understand as much as possible....

Thank you for your time.
