I've moved this to draft for now, since Apple Clang seems to be having a hard time with the noexcept specifiers. Not sure about the Style Guide, maybe I should ask @kimbarrett?

I've added https://bugs.openjdk.org/browse/JDK-8255082 as a blocker for this bug.  As noted there, addressing that
is not as simple as just saying "yes, we can use noexcept".

And no, we're not going to enable exceptions in HotSpot.

I'd be interested in hearing what problems you've run into with Apple clang wrto noexcept.
