Just a thought.

Considering the amount of work Shenandoah developers are putting into
making sure that shared code is reduced to a minimum, it seems like a
great opportunity to synchronise and make the GC interface even more
abstract.

I understand there's little interest in refactoring the CMS code if
it's considered dead anyway (at least for Oracle), on the other end it
seems that you still need to at least do part of this work, and the
long term benefit seems to warrant a look at this option.

Cheers,
Mario
