WM_Class missing, so not compatible with Gnome Dash

[adrienneteicher]

Hello
when I load xjadeo on Gnome (Ubuntu 20.04) and I look at the Dash where it shows running programs, xjadeo has no icon and is referred to as "unknown".
I believe this is because xjadeo does not have the WM_Class set.

If I run in a terminal
$ xprop WM_CLASS

and then click on the xjadeo icon, xprop says:

WM_CLASS: no such atom on any window.

This is a minor problem mainly affecting my mild obsessive tendencies :)
