Hello,
Please review the fix to the following issue:
https://bugs.openjdk.java.net/browse/JDK-8239836
The proposed changeset is located at:
https://cr.openjdk.java.net/~naoto/8239836/webrev.00/
It turned out that 'transitionList' is not necessarily a superset of
'standardOffsetTransitionList', as in some occasions where a standard
offset change and a savings change happen at the same time (canceling
each other), resulting in no wall time transition. This means that the
"rules" in the sample code is a valid ZoneRules instance.
However, there is an assumption in ZoneRules where no (wall time)
transition means the fixed offset zone. With that assumption, the
example rule is considered a fixed offset zone which is not correct. So
the fix proposed here is not to throw an IAE but to recognize the rule
as a valid, non-fixed offset ZoneRules instance.
