Could this be specific to gradle (you are using a pre-release version)? CI runs on GraalVM 21 without issues: #983
Gradle seems to maybe not pick up the META-INF/versions/9 files from the multi-release jar, where the SqliteJdbcFeature class is located.

[lost22git]

Maybe I need to invite a gradle expert @melix to help take a look at this issue

[asm0dey]

@kkriske I have the same issue in my application, without gradle.

My workflow is roughly the following:

> /usr/lib/jvm/java-21-graalvm/bin/java -agentlib:native-image-agent=config-output-dir=META-INF/native-image -jar build/libs/opdsko-all.jar
# some logs here, also performing a couple of curl requests to warm tha application up a bit
> /usr/lib/jvm/java-21-graalvm/bin/native-image -jar build/libs/opdsko-all.jar

Finished generating 'opdsko-all' in 2.8s.

Tried the same with official Liberica NIK, without success either

It seems to me that even native-image does not pick up this META-INF/versions/9 , but I checked it's there in the jar. I can share the project if you're interested

[kkriske]

I'll try to find some time to take a look, if you share the project.
I'm using this in native-image without issues, on jdk 21, through gluon substrate but I doubt that should make a difference.
I am using it through a classpath build, rather than a jar build though.

[asm0dey]

I get the error on this project: https://github.com/asm0dey/opdsko
I tried both gradle plugin and native-image approaches, nothing works and, for what's worse, I don't know how to debug it
