Looks fine, except:

What is this removal? It does not seem related:

 248 ShenandoahAllCodeRootsIterator ShenandoahCodeRoots::iterator() {
 249   return ShenandoahAllCodeRootsIterator();
 250 }
 251
 252 ShenandoahCsetCodeRootsIterator ShenandoahCodeRoots::cset_iterator() {
 253   return ShenandoahCsetCodeRootsIterator();
 254 }
