GluonFX, native image for windows and CDI

Question

I am trying to create a native image for windows for an existing JavaFX application using maven. I have successfully created native images for windows for smaller applications, so the general prerequisites should be ok (see details about my environment below).

This time CDI (weld implementation) comes into play and I am running out of ideas how to solve problems that apparently seem to be related to CDI.

In my build process I always execute "mvn gluonfx:runagent". This helped to solve a couple of

"could not resolved <type> for reflection configuration"

issues in a semi-automatic way. Unfortunately it did not solve all of them.

I managed to solve some further cases by explicitely loading some types with Class.forName(...). But I still did not catch all cases successfully. However, I noticed that among the remaining types there are

• jakarta.enterprise.event.Event and
• jakarta.enterprise.inject.Instance

or to be more precise

• jakarta.enterprise.event.Event$WeldEvent$Proxy$_$$_Weld$Proxy$ and
• jakarta.enterprise.inject.Instance$Provider$WeldInstance$Proxy$_$$_Weld$Proxy$.

The other types are custom types that observe custom CDI events. So I guess I have a problem with CDI and native image. I also "loaded" the types explicitely with CDI.select(...). Does anybody have an idea of how to proceed from here?

Environment:

• Windows 10 / 11
• Visual Studio 2022 Developer Command Prompt v17.0.6
• OpenJDK Runtime Environment GraalVM CE 22.0.0.2 (build 17.0.2+8-jvmci-22.0-b05)

Please let me know if I can provide further information.

edit 1:

I forgot to mention that a native executable (.exe) can be created successfully. Unfortunately the .exe file does not start the application.

edit 2:

I just tried mvn gluon:nativerun. I guess that starts the .exe file and prints out some logging and stuff. Is that correct?

However in the logging I can see that weld finds six META-INF/beans.xml files and complains:

Exception in thread "main" java.lang.IllegalStateException: WELD-ENV-000033: Invalid bean archive scanning result - found multiple results with the same reference: resource:META-INF/beans.xml

I can see that five custom .jar files I depend on contain META-INF/beans.xml files. They are copied to

target\gluonfx\x86_64-windows\gvm\tmp\deps

by gluonfx:compile. What am I supposed to do about duplicate beans.xml files? BTW: duplicate beans.xml files are no problem when running the app in the JVM.

edit 3:

I created a small reproducer that can be found here. It is a multi-module maven project. main module defines a small javafx app that depends on lib1 and lib2. The lib modules are empty except from a META-INF/beans.xml inside each of them.

The .exe file is created but does nothing if invoked directly. When invoked via gluonfx:nativerun the log output is like this:
