There is a Kilimanjaro of tedium in building changes like these that are
implemented across all the basic types. Thank you for taking this on so
A few comments.
- Inconsistent @since declarations. Both "9" and "1.9" are used. I know
Henry Jen was working on normalizing this for the -platform javac work,
but am uncertain what was chosen. It is perhaps time to drop the "1."
- Have you done side by side textual comparisons of the docs and
implementations to make sure there are only expected differences of
types and semantics (== vs equals vs compareUnsigned)? It's easy for an
error to creep in as you go through many iterations by forgetting to
make a fix in one implementation.
- I apologize if this was discussed earlier in the thread but why is the
comparison of floats and doubles done by first == operator of the int
bits and only then the compare method ? It would seem that the compare
method could use this same technique if it wanted. Why not do the same
for unsigned comparisons since == would also work for those?
I am *REALLY* looking forward to using these!
