Test: Built the Shenandoah-patched tree with --with-jvm-features=-shenandoahgc. Then: java -XX:+UnlockExperimentalVMOptions -XX:+UseShenandoahGC --version Error occurred during initialization of VM Option -XX:+UseShenandoahGC not supported Also, we regularily build minimal and zero, and those disable Shenandoah too, that's how we know this works reliably.
