Windows 11: Notifications vanishes after few seconds.

[Davide Perini]

I wrote to Microsoft and they suggested to use the New APIs 
(ToastNotification) meant for the purpose

https://learn.microsoft.com/en-us/windows/apps/design/shell/tiles-and-notifications/toast-notifications-overview 

https://learn.microsoft.com/en-us/windows/apps/design/shell/tiles-and-notifications/send-local-toast-desktop-cpp-wrl

Shell_NotifyIcon API is clearly unsupported after 25/30 years on a 
modern OS.

If you are a Java programmer, you can't send an OS notification.

OS Notifications are very crucial to most apps this days,
I can't imagine how Java can overlook it.

Since you don't accept it as a bug (Oracle is closing all the bug 
reports from people on this),
I opened a feature request on this in the hope that someone wise will 
look at it.

Kind Regards,
Davide
