java.lang.UnsatisfiedLinkError: com.sun.glass.ui.gtk.GtkApplication._isDisplayValid()Z in JavaFx

Question

I have a machine with Ubuntu 16.10 (yakkety) and it runs a javafx application perfectly. but I'm getting this exception when I try to run the same application in another machine with Ubuntu 18.10 (cosmic) even though I have the same openjfx package (8u102-b14-1). Other openjfx bionic packages don't work either.

Run command:

java -jar target/app.jar

Output:

Does anybody know how to solve this?

In Ubuntu 18 I downgrade openfx, libopenjfx-java, libopenjfx-jni:

sudo apt-get install libopenjfx-java=8u161-b12-1ubuntu2 \
                     libopenjfx-jni=8u161-b12-1ubuntu2 \
                     openjfx=8u161-b12-1ubuntu2
