That could be due to jdk-8 vs. jdk-11, or an update of the jedit_build
components.

Can you shuffle these versions a bit, to find out where the change
happens in the history?


Myself, I do not really understand how these things work. E.g. I have
recently switched to Budgie Linux with a new fork of the Gnome Window
manager that is not properly supported by Java 11 / AWT / Swing. I am
merely ignoring some of the drop-outs.

These Java guys are so conservative that it will probably take 10 more
years to get this right, maybe when X11 will be discontinued altogether.
