AFAIU, if I push the same thing to jdk/jdk12, then jdk/jdk would end up with two changesets that
mention 8215724, which is what we are trying to avoid. I know jcheck has the exception list that
allows duplicate bug ids, but I'd desist from duplicating bugids deliberately. Maybe waiting for
jdk-updates/jdk12u to appear and do the normal backport is better all around, and it is not as
painful with the faster release cadence.

I think gatekeepers should decide what to do. Jesper?

I would, it is on our list to backport. But we need to figure out jdk12 first.
