Hi Coleen,
I looked at v2:
http://cr.openjdk.java.net/~coleenp/2019/8235829.01/webrev
Seems good.
But we do a lot of work to keep the nmethod alive while in queue.
Instead we should try copy the data from nmethod and enqueue this copy.
Thus not having to keep the nmethod alive.
Not for this change-set, but a potential future simplification.
Thanks, Robbin
