As discussed in the CR, I think this is closely related to
JDK-8160404.  I think the change to the RelocationHolder constructor
being suggested here may be just papering over a symptom of that other

And I suspect that if JDK-8160404 were fixed then there wouldn't be
any warnings in make_raw to be addressed in what looks to me like a
kludgy workaround.

That all makes me not a fan of the changes being proposed here.
