I went ahead and added the minimum version check. I can rollback if unwanted.

I've compiled it simulating a minimum. The output is:


java @build/run.args -Djdk.gtk.verbose=true -jar apps/samples/Ensemble8/dist/Ensemble8.jar 
checking GTK version 3
trying GTK library libgtk-3.so.0
using GTK library version 3 set libgtk-3.so.0
Glass GTK library to load is glassgtk3
ERROR: Minimum GTK version required is 3.24.34. System has 3.24.33.
