Я использую этот код для окна:

Это мой файл build.gradle:

Я попытался передать-XstartOnFirstThread в качестве опции виртуальной машины, но
независимо от того, что я делаю, при запуске программы я не получаю ошибок,
но окно не фокусируется и не отображается.

Когда я нажимаю на окно java в своей горячей панели, ничего не происходит.

I have done several hours of googling, but there is no answer to my specific
circumstances.

The only thing that I have found is that it is a problem with Mac OS.

Any advice would be grately appreciated, thank you.
