RFR 9: 8133022: Instant.toEpochMilli() silently overflows

[Ivan Gerasimov]

Hi Roger!

There seems to be another numeric overflow possibility a the line# 1235, 
when 'seconds' is a large negative and 'nanos' is a small positive.

For example,
------------
         Instant inst = Instant.ofEpochSecond(-9223372036854776L, 1);
         System.out.println(inst.toEpochMilli());
------------
prints out 9223372036854775616.


Sincerely yours,
Ivan
