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.
