It is a Wayland issue. On X11 it works correctly. I changed the compatibility to "gnome classic at xorg" (it has to be installed also) and I ran the test command:

Bash:

echo $XDG_SESSION_TYPE

I tried different versions of gnome and when it displayed X11 instead of "wayland" everything worked as expected.
It is also explained here:

It's worth trying if you haven't already don't know the details, but it definitely works differently than Crtl+v. But it's not new enough to have been tailored for Wayland, so fingers crossed.

Hi... Thanks for answering. If I try your solution then I get "symbol not found". Maybe you are using another class.
In oracle site it displays this information:

Robot (Java SE 11 & JDK 11 )
