Notification no longer appears in the Windows 11 notification center

[Aleksei Ivanov]

Hi Davide,

I ran your test again on Windows 10 and 11, and the results are 
different. In both cases, I used a recent build of Java 22, which is the 
mainline.

On Windows 10, the notification goes to the Action Center, it stays 
there until I explicitly dismiss it.

On Windows 11, the notification doesn't go to the Notification Center, 
it's completely gone as soon as the toast disappears.

This coincides with what you stated in the bug description.


I added this analysis to the bug. As I explained there, Java uses 
Windows Shell API to display a notification. This API is available since 
Windows 95, and it  provides no control whether the notification 
disappears or goes to the Action Center; after all, the Action or 
Notification Center didn't exist until Windows 8.

So, the status Cannot Reproduce seems wrong. At the same time, there's 
nothing we can do about it.


The “Display the Notification” [1] section explains how to display a 
notification, this is what Java does.

Does the Windows SDK sample, NotificationIcon Sample [2], behave the 
same way?
