I have a JavaFX 8 project which I develop on Windows 10 with NetBeans 8.2. The JAR I build from this I have running on an Asus Tinker Board.

With JDK 11 and JavaFX 11 I want to take advantage of a few of the new features and hope for some performance gain. After installing NetBeans 10 and with the help of the tutorial: https://openjfx.io/openjfx-docs/#introduction (section JavaFX and NetBeans > Non-modular with Maven), I have successfully ported and can run the application on my Windows system.

Either via the IDE or with the command prompt:
java --module-path %PATH_TO_FX% --add-modules=javafx.c
ontrols,javafx.fxml,javafx.graphics,javafx.media -jar Praatpaal2-2.0-jar-with-dependencies.jar

Compared to JavaFX 8, the JavaFX modules are now added as modules.

But when I do the same on the Asus Tinker Board (runnning Tinker OS (Debian)), I get the following error:

Error occurred during initialization of boot layer
java.lang.module.FindException: Hash of javafx.base
(d87df23ee5c54c7ff062c4f8572bab8aaf6c1775854662008fccdb993957bcad)
differs to expected hash
(320c5b0ffaf22fec9daf0c3e364f6598631b333fa95015a0f055e1c1c597c05b)
recorded in java.base

There is very little information on this hash mismatch. My suspicion is that it either tries to load the Windows version of javafx.base.jar, or I use org.openjfx in the Maven pom.xml but refer to GluonHQ JavaFX on runtime, or there is something wrong with the modular setup I have.

The dependencies and build part of the pom.xml look like this:

I have tried the 4 JavaFX dependencies with and without classifier. But this makes no difference.
The jar-with-dependencies builds the jar with all dependencies except the JavaFX ones which I add on runtime with the java command I mentioned earlier.

For Java 11 I use:
https://bell-sw.com/pages/java-11.0.2
Microsoft Windows 64 bit for the Windows system
Linux ARMv7&8 32 Bit HardFloat for the Asus Tinker Board

For JavaFX 11 I use:
https://gluonhq.com/products/javafx/
JavaFX Windows SDK for the Windows system
JavaFX armv6hf SDK for the Asus Tinker Board

With the help of José Pereda I remembered I installed the lite version of Bellsoft JDK without the JavaFX modules. I now have the full version with those modules. I assumed I didn't need those since I would refer to the GluonHQ Java FX packages (--add-modules) anyway.

Bellsoft does not contain JavaFX Media so I will now try to use the Bellsoft JDK Java FX modules but add only the Media via --add-modules, though it may be that Media simply does not exist/work for ARM (yet).
