>>> You need to check if shenandoahgc is disabled first - check
>>> DISABLED_JVM_FEATURES list (see code for jvmci).
>> Why? If Shenandoah is disabled, it will be on this list, and therefore
>> not be built (see JvmFeatures.gmk).
> Did you test with --with-jvm-variants=-shenandoahgc to make sure it is
Test: Built the Shenandoah-patched tree with
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.
