Since the hs-comp is finally open, let's get back to this one. Only
Vladimir K. had formally reviewed, plus Vladimir I. had informally
reviewed. I think we need a second formal Reviewer?

Here is the current webrev:

...and here is the changeset (second reviewer is ????):

The code was passing the full JPRT cycle two weeks ago, passed the HS
jtregs back then. It applies cleanly over jdk9/hs-comp now, and builds
successfully with Linux x86_64/fastdebug.

Thanks,
