Does not launch on Ubuntu 18.04.2

[johnjohndoe]

When I try to run the ColorOracle.jar (Version 1.3, May 5, 2018) on Ubuntu 18.04.2 the following error is shown:

Access to the system tray or notification area is not supported on your system.

I found the corresponding code in ColorOracle.java.

Just got the same issue, Gnome 3 does not support classical tray icons (as implemented by java.awt.TrayIcon) anymore and replaces it with app indicators.

The development-less workaround I found relies upon installation of the TopIcons Plus Gnome extension.

On the longer term though, I think that ColorOracle could take advantage of the dorkbox/SystemTray library.

Same on Debian with Enlightenment. I could maybe run it with WindowMaker and the wmdock, but I consider it a bug if it can't run without a tray.

Same bug on ArchLinux with sway WM and waybar
