However, there are some observations in the JBS by @prrace regarding the test which have not been handled


Also I noticed that the test doesn't exit. It appears that the call to

Desktop.getDesktop().setDefaultMenuBar(bar);

is effectively creating another visible window so the AWT thread doesn't exit.

Adding this line below allows the test to exit and should be added to the test
            SwingUtilities.invokeAndWait(() -> Desktop.getDesktop().setDefaultMenuBar(null));
