Can't Open Forge Installer Window Fedora Linux

[gator23]

When I try to open the forge installer using the java -jar command it doesn't work. I'm using Fedora 40.

The log file

If I say --installServer that works but I don't want to install the server.

Edit: Fedora comes with a headless java installed so that's why it wasn't working. I had to install the full openjdk. sudo dnf install java-21-openjdk

I think this could happen if you have multiple java versions installed

Thanks for replying but I only have openjdk 21.0.3

Try the installClient argument, e.x:

java -jar forge.jar --installClient

Yeah I tried that before and it didn't work, but I already solved it with installing the full version of openjdk since Fedora comes with the headless version preinstalled
