Just a few small tweaks left (should be done by tomorrow, I mostly want to confirm the closed community build works without running locally):

  • extract MethodHandles.lookup into local variable in the static constructor
  • maybe inline objCAS2 (should give us more freedom, allow us to backport into 3.3 in the worst case scenario (hopefully not))
