Hi Grayson
I'm not in front of a RHEL box, but have you tried the OpenJDK with a head? Ie not the headless version.
Best, Bridger

Hello --
After upgrading to Fedora 40, I find that I can not run the BaseX GUI. This is against BaseX110-20240426.163243.zip or 10.7

Various attempts to set DISPLAY have not been helpful.
Trying to use OpenJDK 17 produced effectively the same error message at greater length.
Anyone got any suggestions on how to fix this?
Thanks! Graydon
