Description
In order to avoid oracle#6831 in the future we should change our CI or add new testing which compiles Quarkus with a fixed (older JDK). This testing shall use a locally installed maven artifact from the mandrel build org.graalvm.sdk:graal-sdk as built like so:
$ cd sdk
$ mx build
$ mx --suite sdk maven-deploy --suppress-javadoc
Such a CI workflow shall parameterize on the JDK version to use for quarkus (e.g. JDK 11 for Quarkus 3.2) as it's expected to change from one release cycle to the next.
