'GDK_IS_X11_DISPLAY (display)' failed

[bretelemens]

Hi,
running roda-in v2.7.1 on ubuntu 22.04.3 LTS
java version "17.0.9" 2023-10-17 LTS

When I launch application, it seems to have problem opening the window for the user interface.
I get following error message:

Hello, this is an upstream problem related to OpenJDK executing in Wayland. For some reason, you need to pass an environment variable to get it to run with XWayland compatibility.

You can run this from the CLI using the following:

GDK_BACKEND=x11 RODA-in

If you want to create a proper desktop entry for your user, so it can be launched from the GUI, you can do so like this:

cp /opt/RODA-in/RODA-in.desktop ~/.local/share/applications/ && sed -i -e "s|Exec=/opt/RODA-in/RODA-in %U|Exec=env GDK_BACKEND=x11 /opt/RODA-in/RODA-in %U|g" ~/.local/share/applications/RODA-in.desktop

Issue should be solved if JavaFX was updated to version 12 or greater.
Current version, JavaFX 11 got EOL in September 2023. Recommending upgrading to latest LTS version currently 21.
