Weak Ref Processing

[Simone Bordet]

Hi,

I'm preparing for a conference session about Shenandoah (and ZGC), and
I would like to confirm how Shenandoah does Weak (et al.) Reference
Processing.

As far as I understand, weak reference processing is still a STW
operation during the final mark phase, so GC parallel but not GC
concurrent. Is that correct?

Is there any plan to make it concurrent, if not already?

Thanks!
