我正在尝试运行此解决方案 awt System tray以在我的ubuntuu上使用Javafx应用程序） 20.04.3 Lts。我尝试使用OpenJDK 14和17，结果是相同的：

Exception in thread "AWT-EventQueue-0" java.lang.UnsupportedOperationException: The system tray is not supported on the current platform.

尝试解决我发现的问题这个答案：代码> GNOME 3.28（在Ubuntu 18.04中使用）删除了系统托盘。我认为，Ubuntu 20没有系统托盘，这就是问题所在。但是，在屏幕的右上角，我看到以下内容：

。

如您所见，有三个应用程序图标 - 电报，Viber和闹钟。据我了解，这些图标已在系统托盘中显示，所以系统托盘存在。那是什么问题？ AWT不支持Ubuntu 20系统托盘？有人可以解释吗？

I am trying to run this solution (AWT System Tray to control a JavaFX application) on my Ubuntu 20.04.3 LTS. I tried with openjdk 14 and 17, result is the same:

Trying to solve the problem I found this answer: saying that Gnome 3.28 (used in Ubuntu 18.04) removed the System tray. I thought, that Ubuntu 20 didn't have a system tray, and that was the problem. However, in the top right corner of my screen I see the following:

As you see there are three application icons - Telegram, Viber and Alarm clock. As I understand these icons are shown in system tray, so
system tray exists. Then what is the problem? Doesn't AWT support Ubuntu 20 system tray? Could anyone explain?
