@coleenp it is great to see all this code go but I'm unclear about the uses of "protection domain" that have been removed, compared to those that still remain in the hotspot code in particular how CDS still uses it. To be fair I'm unclear what role PD still plays on the JDK side and would not be surprised if it is destined for removal at some point. How do we recognise that the remaining uses of and reference to the PD are still needed and not something we could now delete?
