1 month ago Hello. I am using SystemTray on the ubantu2204 Java 8 application. An error occurred while running this code. SystemTray systemTray = SystemTray.get();
Exception in thread "AWT-EventQueue-0" java.lang.NoClassDefFoundError: dorkbox/util/OSUtil$DesktopEnv at dorkbox.jna.linux.GtkTheme.getIndicatorSize(GtkTheme.java:232) at dorkbox.systemTray.util.SizeAndScalingLinux.getTrayImageSize(SizeAndScalingLinux.java:55) at dorkbox.systemTray.util.SizeAndScaling.getTrayImageSize(SizeAndScaling.java:50) at dorkbox.systemTray.SystemTray.get(SystemTray.java:707) at dorkbox.systemTray.SystemTray.get(SystemTray.java:171)
I guess the reason is the lack of jar package. But I can't find this jar package. Can you provide me with some help? Thank you

Hi
I've been using SystemTray on a Java 8 app for sometime, and recently moved over to Java 21 and seeing an exception that I thought you might be interested in.
Interestingly, when I run the app in a terminal I don't see the exception and things work fine. It is only when I run it in IntelliJ that I see the exception.
