Hi Joe,

Thanks for the detailed explanation.
It really helps reviewing the fix!

Glad to know it helps. I thought this part of spec could be unfamiliar to people.


This looks reasonable to me. One minor nit is that you
could turn:

769 BigInteger maxintAsBigInteger = BigInteger.valueOf((long) Integer.MAX_VALUE);

Good catch!  I was going to do so but then forgot.

I also refactored the check method so that the checks can be done in one loop: 24 lines of code instead of the original 170. I feel good :-)

The other changes are purely clean-up and in one case, JavaDoc.

Hi,

This is a long time compatibility issue: Duration.compare returns equal
for INDETERMINATE relations defined in XML Schema standard
(http://www.w3.org/TR/xmlschema-2/#duration-order) as listed in the
following table:

    Relation
P*1Y*     > P*364D*     <> P*365D*         <> P*366D*     < P*367D*
P*1M*     > P*27D*     <> P*28D*     <> P*29D*     <> P*30D*     <>
P*31D*     < P*32D*
P*5M* > P*149D* <> P*150D* <> P*151D* <> P*152D* <>
P*153D*     < P*154D*



The order-relation of two Duratoin values x and y is x < y iff s+x < s+y
for each qualified datetime s listed below:

 * 1696-09-01T00:00:00Z
 * 1697-02-01T00:00:00Z
 * 1903-03-01T00:00:00Z
 * 1903-07-01T00:00:00Z


The original implementation used Unix epoch, that is, 00:00:00 UTC on 1
January 1970, as s in the above calculation which violated the above
specification. A patch during JDK 6 development added correct
implementation of the spec, but it was unfortunately added after the
original calculation using Epoch time.

*The fix to the issue therefore is simply removing the calculation using Epoch time.* I also consolidated the tedious max field value checks into
a method called checkMaxValue.

*Patch:*

Test:
testCompareWithInderterminateRelation: this is a copy of the JCK test
that tests INDETERMINATE relations.
testVerifyOtherRelations: this is added to verify edge cases, e.g. +- 1
second to the original test cases. For example, to the original test:
PT525600M is P365D <> P1Y, I added "PT525599M59S", "<", "P1Y", and
PT527040M -> P366D <> P1Y, "PT527040M1S", ">", "P1Y"

Below is the test result:
