May resolve SONGKONG-2000.
Allows use of new jpackage tool on windows
Melco working without problem.
Maybe linux issue with posix_spawn, so for SongKong 6.9 release keeping everything at Java 11 except Melco which requires Java 14 to fix JVM crash bug.
Workaround taskBar.Feature.ICON_BADGE_NUMBER seemingly unsupported with Java 14 (maybe a Java bug) but means no longer see a count on the icon
Window titlebar always shown as aqua
Native Dialog always shown as Aqua
Done for Windows.
