Code review: 7012540 (java.util.Objects.nonNull() incorrectly named)

[Brian Goetz]

This ground has been already covered.  "as", "to", etc, are fine for 
conversions -- but by definition this is a conversion will never 
succeed.  At the same time, we need to leave room in the namespace for a 
conversion operation that *will* succeed.  (If we didn't need both, this 
whole conversation would be moot!)  as/to/make are all fine for the 
"carpet-sweeping" version of this method, but that's not what's being 
discussed.
