At a quick glance it looks okay, but I've not looked at it carefully enough to say I've reviewed it.  Given the amount of
discussion I can't agree with it being "trivial".  Small, yes, but with potentially significant impact.  And HotSpot rules
around trivial changes and bypassing some of the review process requires agreement by the Reviewer, of which
there is none recorded in the discussion here.
