This rare OOME with ZGC doesn't reproduce readily and has not reappeared
in the mainline CI. However it has failed twice in Panama testing for
the same reasons. A personal test job also showed that ZGC plus JFR
fails in a more extreme way (VM initialization failure) and that failure
is completely reproducible. Bumping the minimum heap to 11M fixed that
issue so that is what I will commit for this fix.
Testing via tiers 1-3 plus manual on Linux.
Thanks,
David
