I haven’t tried with raspberry pi. I just got my rpi today and haven’t found an SD card to install an OS.
I saw this is quite an old thread maybe you can try to install the version recommended by Erel.

Raspberry Pi with Java 11

Running UI apps on Raspberry Pi with Java 11 is relatively simple. 1. Download Liberica JDK. Download the lite version: https://github.com/bell-sw/Liberica/releases/download/11.0.1/bellsoft-jdk11.0.1-linux-arm32-vfp-hflt-lite.tar.gz 2. Copy it to the RPi and unpack it: tar -xvf...

I ran into same error when creating release.
I am running 32bit Raspberrypi OS on Raspberry Pi 4B and using 32bit Belsoft Liberica OpenJDK 11.0.14. If I am not mistaken, B4JPackager11 requires 64bit Java.

Bash: 
pi@raspberrypi:/usr/java/jdk-11.0.14.1-full/bin $ java -jar tempjars/B4JPackager11.jar tempjars/packager.json
B4JPackager11 Version 1.21
Exe name: WebAPIClient.exe
InputJar: /usr/java/jdk-11.0.14.1-full/bin/tempjars/WebAPIClient.jar
Folder not found: /usr/java/jdk-11.0.14.1-full/bin/../javafx/javafx-jmods

I follow yours instructions and now I can run the project (jar). But still I have a problem with B4jPackager and as you already secribed - I'm sure that is problem with java 64 bit and B4jPackager...

When I run B4j over bridge, I receive still error:



In worst case I will create bash script to install all needet java jars to every raspberry pi machine and run created jar (without making the installation)... This will be most easyest way...

Ya, I also get the same error as yours.

Bash: 
Error: Modules dio and jdk.dio export package jdk.dio.power to module jrt.fs

Something related to jdk.dio that I can't find any solution yet.

In case anyone has encountered the following error using Bellsoft Liberica Full JDK 11.0.14.1+1 ARM 32 bit for Linux:
B4X: 
Folder not found: /usr/java/jdk-11.0.14.1-full/bin/../javafx/javafx-jmods

Modify B4JPackager11 source code as:
B4X: 
Sub AppStart (Args() As String)
    ...
   
    Java14 = Ver.StartsWith("14")
    'JavafxJmods = ReplaceSlashes(File.Combine(java, "..\javafx\javafx-jmods"))
    'JavaFXLibs = ReplaceSlashes(File.Combine(java, "..\javafx\lib"))
    JavafxJmods = ReplaceSlashes(File.Combine(java, "..\jmods"))
    JavaFXLibs = ReplaceSlashes(File.Combine(java, "..\lib"))
   
    ...
End Sub

I think I found a solution.
Delete (or rename) the following files inside /usr/java/jdk-11.0.14.1-full/lib:
dio.jar
jrt-fs.jar

Then run B4JPackager11.jar

Voila! It compiles!
Click to expand...
Not sure it is a correct way but at least I can compile the jar using B4JPackager11.

Answer from SO.
Try to remove jrt-fs.jar from the directory of jdk9. I did it in Project Structure in IntelliJ IDEA and it works fine for me
