Unable to run JavaFX application on Raspberry Pi 4B

Question

I have developed one JavaFX touchscreen application with screen size 800x480 which runs fine on RPi 3 with the Raspberry Pi 7" Touchscreen Display in the default resolution (800x480). Now I am trying to run it on RPi4 for the same touchscreen (800x480) and encountering the following exception every time I run the JAR file:

Exception in thread "JavaFX Application Thread" java.nio.BufferOverflowException

What could be the cause?

My setup:

1. Raspberry Pi 3b (running 2017-07-05-raspbian-jessie)
2. Raspberry Pi 4b 4GB (running 2019-07-10-raspbian-buster)
3. Raspberry Pi 7" Touchscreen Display
4. I'm using jdk 1.8.0_221 (build 1.8.0_221-b11) and the Gluon JavaFX Embedded SDK(8.0.72) on both RPi.
5. Both RPi boot to the CLI (auto login)

6. On the RPi4, I'm launching the application using the following command:

   sudo java –Dprism.order=sw -jar AMS.jar
