Oh, makes sense :) Is that mentioned in the paper and I missed it? If not, it might deserve a footnote, as the difference is glaring.

BTW, would Graal really become available as a stock-HotSpot plugin in Java 9 thanks to JEP 243? I see things are ready on Graal's end[1], but are they on HotSpot's?
