[15] RFR: 8239520: ValueRange.of(long, long, long) does not throw IAE on invalid inputs

[Roger Riggs]

Hi Naoto,

The CSR looks ok.

In the implementation ValueRange.of: 148-150; I would omit the check 
here since
it invokes the 4 arg form and does the same check.
The difference in exception message is not worth the extra code.
Though it would help if it said that the 3 arg form is the same as the 4 
arg form with the same first two args.

In the test TestDateTimeValueRange.java, the separate test case is 
(mostly) redundant with the added case at line 187.
(Though that assumes the 3 arg form calls the 4 arg form; as does the 
lack of any other testing of the 3 arg form).

Also,
It might be useful to verify that each of the test cases 179-186 trigger 
only 1 of the range checks.
If a test case would fail more than 1 of the conditions then it might be 
never be testing each if statements.

Thanks, Roger
