This is to simplify `TrayIconScalingTest.java`. 1. Rename `createAndShowGUI` to `createAndShowTrayIcon` which is more specific. 2. Move creating tray icon to the top. 3. Streamline PassFailJFrame with the chained calls, including `awaitAndCheck`. 4. Ensure tray is not null before removing the icon. 5. Pass AWTException as the cause in the wrapped exception.
Previously, before the builder pattern was introduced, `PassFailJFrame.positionTestWindow` had had to be called to show the instructions UI. It's not required any more. Additionally, it has the effect of moving the instruction frame to the left, which doesn't look good and sometimes results in positioning the instructions outside of the screen bounds if the screen resolution is low. With the builder pattern, the call to the `build` method shows all the registered windows on the screen, including the instruction frame. Since there's no secondary UI, the instructions remain in the centre of the screen. ------------- Depends on: https://git.openjdk.org/jdk/pull/18206 Commit messages: - Pass AWTException as the cause in the wrapped exception - Re-arrange the code in TrayIconScalingTest.java Changes: https://git.openjdk.org/jdk/pull/18224/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=18224&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8327924 Stats: 27 lines in 1 file changed: 10 ins; 11 del; 6 mod Patch: https://git.openjdk.org/jdk/pull/18224.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/18224/head:pull/18224 PR: https://git.openjdk.org/jdk/pull/18224
