Windows 11: Notifications vanishes after few seconds.

[Davide Perini]

Thanks for the explanation Aleksei
but can you explain me what is the OpenJDK direction please?

Suppose that you have a feature like this one, a simple notifications.
Java worked well with Windows notifications until Win10,
then Microsoft changed the APIs for notifications in Win11.

Isn't OpenJDK supposed to adapt to the new Windows APIs?

Does OpenJDK supports Windows 11 or not?

It's a little "weird" to close an issue by saying that Java uses the 
same way to do the same thing since Windows 95
and that it's a Microsoft problem if they changed the way to send 
notifications to the OS.

Java should support Microsoft Windows, it isn't Microsoft Windows that 
should support Java,
isn't it?

Other languages adapted their APIs for the new notifications system, 
like everyone should expect from a modern language,
after 2 years from the release of Win 11,
Oracle says that it worked since Windows 95, so it is ok to have a 
broken API in JDK because it worked before, they are the ones who broke 
it (Microsoft).

Does Java offers a correct way to send Notifications in Win10? Answer: Yes
Does Java offers a correct way to send Notifications in Win11? Answer: No
Does other languages offers a correct way to send Notifications in 
Win11? Answer: Yes
Does current JDK APIs works as expected in Win11?
Answer: No because JDK uses an old API born with Win95 (30 years ago + 
or -) with a new OS born in 2021, this results in an unexcpected 
behaviour that doesn't work as supposed initially by the API.

In the bug report you wrote:
"I can't see what Java can do to change the behaviour."

The answer is:
"By implementing the correct API for the correct OS".


Java is currently not able to correctly send a Notification in Windows 11.


I see a bug there, if you don't see it,
I'm pretty worried of the new JDK direction.

Thanks
Davide
