You are right. While looking into JDK-8324799 I found a couple of headers that
were only included by an associated .cpp that wasn't built, but the .cpp was
instead included by other files that were built. I mis-remembered this was one
of those, but apparently not. I'll delete the files, update the bug, and make a new PR.
