<!--
jcstress-core ships its own annotation processor (JCStressTestProcessor) that
generates the *_jcstress.java harness classes from @JCStressTest/@State/@Actor.
On JDK 21 javac still finds it implicitly via the classpath (with a warning that
this is going away). On JDK 25 that implicit discovery is gone: no warning, no
error, the processor is just silently never invoked and target/generated-test-sources
stays empty. Verified with plain javac on both JDKs while building this repo -
see the versions callout in the post. annotationProcessorPaths is what makes it
work on both.
