> The change made in [JDK-8288723](https://bugs.openjdk.org/browse/JDK-8288723) > seems innocuous, but it caused this performance regression. Partially > reverting the change (ones that involve `computeIfAbsent()`) to the original. > Provided a benchmark that iterates the call to `ZoneOffset.ofTotalSeconds(0)` > 1,000 times, which improves the operation time from 3,946ns to 2,241ns.
