I reverted this patch. It caused regressions.
I am going to look into the bug I had and try to think of a better
solution.
2006-05-10 Lillian Angel <[EMAIL PROTECTED]>
* java/util/SimpleTimeZone.java: Reverted patch.
(SimpleTimeZone): Throw exception if startMonth ==
endMonth.
(SimpleTimeZone): Likewise.
(checkRule): Rewritten to properly check all values (more
efficently).
This code is now more stable, at least less buggy than before.
Fixed API documentation.
(setStartRule): Moved checkRule call to end.
(setStartRule): Likewise.
(setEndRule): Likewise.
(setEndRule): Likewise.
