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

I do hope that method parameters are not eagerly gc'ed before the method returns They are -- that's what reachabilityFence() is for. I don't think that constructors have any special rules, and nor should they. Andrew.
