Multipart Class Defined Outside Resource Implementation Fails with CNFE "Populator"

Describe the bug

When I define a class meant to be used as a payload in both my REST client and resource I get a CNFE stating that the “populator” could not be located. If I put the class with the resource it works fine.

Referencing a conversation with Michal on Google Groups.

Issue 1 demonstrates the error / Working 2 demonstrates what worked:

reproduce-issue1.zip reproduce-working2.zip

NOTE: Hopefully I did not mix up my reproducers.

Expected behavior

Class defined in a separate module can be used as the payload from the client and in the resource.

Actual behavior

Class not found exception - “Populator” when the payload is defined in another module.

ClassNotFoundException: io.platform.api.publish.FilePackage_generated_populator

How to Reproduce?

Run mvn clean install on the issue attached above

Output of uname -a or ver

Ubuntu / WSL

Output of java -version

JDK 11 in the POM / 15 as the default.

GraalVM version (if different from Java)

No response

Quarkus version or git rev

2.0.3.Final

Build tool (ie. output of mvnw --version or gradlew --version)

3.8.1

Additional information

I forgot to include the Jandex plugin in my reproducer but my modules all are invoking it (and I see the IDX file). I have also tried adding a beans.xml but that did not help. Anything but the multipart payload seems to work though when separated between an API jar and the service jar.
