I was a bit surprised it isn't used more, but couldn't come up with any
missing uses.

The change violates the Law of Demeter, but that's pretty much par for HotSpot
code. (I think it's a useful design rule and yet often fail to follow it
myself.) Just support of whitebox testing isn't a great rationale for a public
API function if it can be done without.

So looks good.
