8225790: Two NestedDialogs tests fail on Ubuntu

[pankaj-bansal]

Two NestedDialog tests are failing on Ubuntu 20.04 intermittently. I am able to reproduce the issue locally also sometime.

Tests are creating a frame and then create multiple dialogs. These tests are using classes VisibilityValidator and Waypoint (present in test/jdk/java/awt/regtesthelpers) for doing basic operations like waiting for a Frame/Dialog to become visible, doing a mouse click on a Frame/Window. Also, the test is not using Robot waitForIdle properly. so making the test less stable.

I have removed the lot of unnecessary code from the tests. Also, I have added proper AutoDelay on Robot and used waitForIdel properly. I have also removed the class VisibilityValidator and Waypoint. These classes were added with in test/jdk/java/awt/regtesthelpers when these tests were added. I don't see any use of these classes. No other test is using these classes at all and there is too much code in these classes.

I have run the multiple iterations of the test on mach5, it passes successfully. I have also run a full job to make confirm VisibilityValidator and Waypoint are not being used anywhere else.
