It turned out the way I was configuring things I need to run tier2 to actually use it.

And it seems to not work on Windows.  But that’s not too surprising, given this from os_windows.cpp:
4095  if (UseNUMA && !ForceNUMA) {
4096    UseNUMA = false; // We don't fully support this yet
4097  }

I haven’t looked further; I think that’s out of scope for JDK-8242459.
I’ll followup with a separate bug.
