> This is stemming from the PR: https://github.com/openjdk/jdk/pull/14211 where > aggressive GC can cause NPE in `BaseLocale$Key` class. I refactored the > in-house cache with WeakHashMap, and removed the Key class as it is no longer > needed (thus the original NPE will no longer be possible). Also with the new > JMH test case, it gains some performance improvement: > > (w/o fix) > > Benchmark Mode Cnt Score Error Units > LocaleCache.testForLanguageTag avgt 20 5781.275 ± 569.580 ns/op > LocaleCache.testLocaleOf avgt 20 62564.079 ± 406.697 ns/op > > (w/ fix) > Benchmark Mode Cnt Score Error Units > LocaleCache.testForLanguageTag avgt 20 4801.175 ± 371.830 ns/op > LocaleCache.testLocaleOf avgt 20 60394.652 ± 352.471 ns/op
