I can follow that concern. My problem is that I cannot reproduce the failure. Note also that the OOME is successfully generated during object reallocation a couple of times before (search "run args" in attachments to the JBS issue). I'd think the approach to prove the OOME during the PopFrame/ForceEarlyReturn [1] is relatively reliable knowing how smart GCs try to be with avoiding it. I've tried to make it even more reliable with a second commit in this pr. Would that be ok? Maybe you would know a better way? Thanks, Richard.
