I took the command-line generated by Eclipse and ran it in a terminal:

/usr/lib/jvm/java-11-openjdk-amd64/bin/java --module-path /usr/share/openjfx/lib --add-modules javafx.controls --add-opens javafx.graphics/com.sun.javafx.tk=ALL-UNNAMED --add-opens javafx.graphics/javafx.stage=ALL-UNNAMED --add-opens javafx.graphics/com.sun.javafx.tk.quantum=ALL-UNNAMED --add-opens javafx.graphics/com.sun.glass.ui=ALL-UNNAMED -Dfile.encoding=UTF-8 -p /usr/share/openjfx/lib/javafx.base.jar:/usr/share/openjfx/lib/javafx.controls.jar:/usr/share/openjfx/lib/javafx.fxml.jar:/usr/share/openjfx/lib/javafx.graphics.jar:/usr/share/openjfx/lib/javafx.media.jar:/usr/share/openjfx/lib/javafx.swing.jar:/usr/share/openjfx/lib/javafx.web.jar -classpath /home/gmseed/eclipse-workspace/JOGL_JavaFX/bin:/home/gmseed/programming/libs/jogl/jogamp/jogamp-fat.jar org.jogamp.joglojfx.App

and it worked, but still issued the warning:

(java:31236): Gdk-WARNING **: 14:25:33.909: XSetErrorHandler() called with a GDK error trap pushed. Don't do that.

However, I'm still left wondering why it won't run in Eclipse, when using Eclipse's own generated cmd-line command!!

After a bit of googling I found this related post:

and tried adding:

export LIBGL_ALWAYS_SOFTWARE=1

to my bashrc, but it made no difference to the Eclipse run.
