I was following the steps given at Gluon Documentation to run JavaFX on Raspberry Pi 4 via DRM. I downloaded the JavaFX EA 16 builds from here.
javafx.properties file :
javafx.version=16-internal
javafx.runtime.version=16-internal+28-2020-11-10-180413
javafx.runtime.build=28
After cloning the samples repository containing hellofx, I compiled it via javac (according to the steps) and then ran this command to run it using DRM:
sudo -E java -Dmonocle.platform=EGL -Djava.library.path=/opt/arm32hfb-sdk/lib -Dmonocle.egl.lib=/opt/arm32fb-sdk/lib/libgluon_drm.so --module-path /opt/arm32fb-sdk/lib --add-modules javafx.controls -cp dist/. hellofx.HelloFX
However, this caused the following error :

It seems that while loading libgluon_drm.so in JavaFXSDK/lib/ fails at getNativeWindowHandle
What's weird is that after I ran sudo apt install libegl* mesa* libgl*, it actually succeeded but was asking me to set variable ENABLE_GLUON_COMMERCIAL_EXTENSIONS as true, which I had already done.
However, after rebooting, it started showing the same error.
I am using a Raspberry Pi 4 Model B with 2GB RAM. It is running on Raspberry Pi OS 32-Bit with desktop.
I had performed all of this on a clean installation.
