Changed the title a lot I know but this bug is the closest.

Good work tracking that down. I'm not a Freebsd committer, so I can't sponsor
these patches into the Freebsd ports tree. However, if you've already agreed
to, or are willing and capable of agreeing to Oracle's OCA, I'll sponsor
getting the patch into the bsd-port openjdk repository.

Awaiting feedback from my company on signing up to the OCA.

It may be that they would be happy for me to individually sign the OCA and
allow me to submit such patches as my own work but it needs to go by legal.

There's a bunch of stuff in the OCA about surrendering rights on patentable
material etc. which I'm sure only applies to the contributions made but it's
the sort of thing that brings out legal teams in a rash.

As far as these changes go, this it Hotspot and a body of GPL work so the
patches should be made available anyway and I would be happy for any other
committer to add this to either the bad-port upstream or to the patch set here.

Andrew, thanks for working on this and for the patches. I'd love to upstream
this, so please let me know if you have success with getting the OCA signed
either personally or at a company level.

I'll get a copy of the OCA signed personally I think as everybody here says
that's probably the best way to proceed.

My OCA has been processed and I now appear on the OCA web page as 'Andrew Smith
- OpenJDK' and am happy for you to sponsor these changes should you wish.
