Yes, this appears to be a massive change involving what may largely be 
stylistic matters (if that is what Assert.assertMumble << assertMumble is all 
about).  On first glance, it makes an excessive change that is extremely 
difficult to comprehend and review.

What are the practices around expecting small focused single-purpose changes 
and, in this case, a small change that addresses the stated purpose of the 
commit with regard to the contract for FastMath.round() and its testing?

Is this [VETO] territory, and would the committer be asked to revert the change 
and break it down?

I ask this because I don't understand the Commons culture and practices in 
order to know.

Oh, and is there a JIRA about this (the Math.round contract) or some other way 
to tie in whatever scholarship and traceability is involved in the specialized 
case of [MATH] software?  (I may have missed this - sorry for asking if already 
answered.)
