@tomas-langer I feel this is a general issue, when I ran the /etc/scripts/test-quickstarts.sh on my own mac book I got the same error (also on the master branch). Is it ok to assume you gonna tackle it from here and eventually merge it?

I will try to reproduce and pinpoint the issue.

@eiselems can you please share the exact version of GraalVM you use? I cannot reproduce this on my Mac, so probably a difference in the version...

Thanks

Used one quite similar to what the CI reported ( JAVA_VERSION: 21 GRAALVM_VERSION: 21.0.3)

Personally I used GraalVM CE 21.0.2

❯ ./java --version
openjdk 21.0.2 2024-01-16
OpenJDK Runtime Environment GraalVM CE 21.0.2+13.1 (build 21.0.2+13-jvmci-23.1-b30)
OpenJDK 64-Bit Server VM GraalVM CE 21.0.2+13.1 (build 21.0.2+13-jvmci-23.1-b30, mixed mode, sharing)

running on a M1 Macbook Air

❯ ./etc/scripts/test-quickstarts.sh
...

Assuming usage of sdk man

sdk install java 21.0.2-graalce
export GRAALVM_HOME=/Users/marcus/.sdkman/candidates/java/21.0.2-graalce

[tomas-langer]

Unfortunatelly cannot reproduce on my Macbook yet

[tomas-langer]

Finally managed to reproduce, but only with this branch.

[tomas-langer]

The problem is caused by update to new annotations for features without changing the annotation processor paths (the old processor would not understand the new annotations, and it produces an empty file, which causes failure in GraalVM extension)

[eiselems]

Ok I missed doing this on all modules, that makes sense, thank you! Let's see if everything builds.

[tomas-langer]

@eiselems thanks for the contribution!
