BTW in the implementation PR, Alexander wrote


The [DENY case](https://github.com/azvegint/jdk/blob/482471df61490120590bc49886f76dc99c3d7dd8/src/java.desktop/unix/native/libawt_xawt/awt/screencast_portal.c#L586-L591) propagated to java and we are throwing the security exception.

So I interpret this as there is a use case for the exception.
