Gluon Native DRM javaFX error, Unable to start up DRM based JavaFX Native app

Question

I found this answer, which is really close, but not my problem. I too have followed the same instructions, from a fresh install.

Following the instructions here, I have set up 512MB of GPU ram, and am connected via ssh. There is no desktop running, it's entirely booted to CLI. Perhaps there's some undocumented steps by running the raspberry pi os lite image?

Instead of library failures, I get:

pi@deskscreen4:~/samples/CommandLine/Modular/CLI/hellofx $ 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

I do not have the DISPLAY environment variable set, I have exported the GLUON commercial env var:

pi@deskscreen4:~/samples/CommandLine/Modular/CLI/hellofx $ env  | grep GLUON
ENABLE_GLUON_COMMERCIAL_EXTENSIONS=true
pi@deskscreen4:~/samples/CommandLine/Modular/CLI/hellofx $ env  | grep DISPLAY
pi@deskscreen4:~/samples/CommandLine/Modular/CLI/hellofx $

When I did this in the past on java8, I did not have any X-Windows environment installed, and I used a setting like so:

 -Dembedded=monocle \
 -Dglass.platform=Monocle \
 -Dprism.verbose=true \

EDIT: I have found other questions that are similar, but not the same. If I specify those options, I get a different error, about how it's unable to load the EGL platform:

What did I do wrong? Why does it insist upon trying to load GTK as if a desktop environment is there?

Well, I figured it out.

I was using the Bellsoft liberica JDK. That apparently doesn't have the right things, or has conflicty things.

I solved my problem by switching to an adoptopenjdk java11 build. Things fired right up perfectly with some library errors. It fell back to the software pipeline, but that's a known fix:

WARNING: java.lang.UnsatisfiedLinkError: /opt/arm32fb-sdk/lib/libprism_es2_monocle.so: libGLESv2.so.2: cannot open shared object file: No such file or directory

An apt install libgles2 libgles2-mesa later, and I have problems that other people have seen and solved
