RFR 9: 8138696 : java.lang.ref.Cleaner - an easy to use alternative to finalization

[Roger Riggs]

Hi Andrew,

So then is is correct to conclude that the gc does examine fields in 
instances
still being constructed to determine reachability?

How is that we have gone so long without needing reachabilityFence?
Or is it just because optimizers have taken so long to get a perfect 
view of reference scope?

Thanks, Roger
