<Swing Dev> [OpenJDK 2D-Dev] [12] Review Request: 8213110 Remove the use of applets in automatic tests

[Sergey Bylokhov]

Hi, Phil.

Thank you for review, see my comments inline:

> You discuss the life cycle of an applet in jtreg
> -----------
>    - Call init() and start() methods of the Applet
>    - Waits for 2 seconds
>    - Call stop() and destroy() methods of the Applet
>    - Dispose the frame

Because most of our tests override init() and start() and skip stop()/destroy().

> Do you really mean jtreg() kills the applet just two seconds after start() returns ?

After two seconds it will call stop()/destroy() then dispose the frame and exit.

In this awt test it is not necessary, but some other tests(for Swing library) should be updated at some point.

In this test it is needed because otherwise "fd.setVisible(true)" will block the "main()" thread.
