> A rather large startup regression was introduced in 23-b13 from > [JDK-8309622](https://bugs.openjdk.org/browse/JDK-8309622). Some of that has > been dealt with as enhancements such as > [JDK-8330802](https://bugs.openjdk.org/browse/JDK-8330802), > [JDK-8330595](https://bugs.openjdk.org/browse/JDK-8330595) and > [JDK-8330681](https://bugs.openjdk.org/browse/JDK-8330681), which provide > both point fixes and reduce initialization overhead of certain constructs > more generally. The remaining issues stem from a set of lambdas added in code > for `java.util.Locale` and `jdk.internal.util.BaseLocale` causing early > bootstrapping of the lambda infrastructure and a bit of class generation. > > While the remaining overheads are relatively small and borderline acceptable > (< 2-3ms), I think it's still worth acting on them in this particular case > since the amount of added bootstrapping overhead is dependent on which locale > the system runs under, which complicates testing and comparisons due to > relatively large differences in paths taken on different systems.
