Windows 11: Notifications vanishes after few seconds.

[Aleksei Ivanov]

Hi Davide,

The bug that you reported has been moved to JDK project in JBS, you can 
view it as JDK-8315647 [1]. You should've received a link to it.

What kind of answer did you expect to receive?

You already asked this question on this mailing list in August [2]. I 
replied to your question [3]. Nothing has changed since August. It is 
not a bug in Java because a native Win32 app behaves the same way.

I compiled and tested the sample [4], it behaves in Windows 11 as Java 
does: the displayed balloon notification does not go to notification 
centre. However, if I open notification centre while the balloon is 
displayed, it remains there. If I disable "Show notification banners" 
and leave "Show notifications in notification centre" enabled, the 
balloon goes directly to notification centre without displaying a banner.

You can compile and test the sample too:

git clone --filter=blob:none --sparse 
https://github.com/microsoft/Windows-classic-samples.git windows-samples
cd windows-samples
git sparse-checkout add 
Samples/Win7Samples/winui/shell/appshellintegration/NotificationIcon

Navigate to the NotificationIcon folder and open NotificationIcon.sln in 
Visual Studio to compile and run it.

If required, I can attach the compiled version of the application.


I have closed JDK-8315647 as duplicate of JDK-8310352 [5].
