Please Review fix for reduced value parser 8024076

[roger riggs]

Hi,

The java.time reduced value parser does work as expected (issue 8024076)
for chronologies other than ISO.
The base value is assumed to be chronology independent but is not
converted to the requested Chronology before it is used.

Please review:

Thanks, Roger
