Just to be clear, you had no problems with heap locked at max size and
always pre-touch with 12+33?

batch count = 1_000 runs for ~10s.
8 hrs -> batch count = 2_880_000

Make it 2_500_00 and you should be good overnight (I once did precise
math and the "circa" 10s, when multiplied, yielded hours more :)

Do you mean the tip of http://hg.openjdk.java.net/jdk-updates/jdk12u/?

Thanks!
