Deven,
If last time zone ID is cached along with the previously resolved index,
and getZoneIndex does not check the contents of array, it might not work
when zone strings are updated (setZoneStrings). So, to make this change
work properly, you have to reset lastZoneID/zoneIndex in
setZoneStri
I think Yoshito's suggestion make sense, since the getZoneIndex is an
internal method, if there is no manual setting to change the timezone,
The timezone ID won't be changed for one instance of SimpleDateFormt.
I updated the patch webrev[1] for this suggestion and test the
GetZoneIndexTest.jav
