This revision considers any java/javax and org.springframework.lang annotations as not synthesizable upfront, checking not only in isSynthesizable but also at synthesizeAnnotation(Array) level.
Issue: SPR-16933
Empty Maps are preferably initialized without capacity (not initializing them at all or lazily initializing with default capacity when needed).
Issue: SPR-17105
This commit includes an optimization of BeansUtils#instantiateClass
that favors Java reflection for default constructors before leveraging
Kotlin one for finding primary constructors and avoids Kotlin related
conditions when running in Java.
Issue: SPR-17069
This revision limits serializability of derived interfaces, superclasses and type parameters, optimizing for introspection performance instead.
Issue: SPR-17070
Includes tests for parsing all available locales on the JVM, checking toString/toLanguageTag equality between parsed and original locale.
Issue: SPR-7598
Issue: SPR-16651
Like CookieLocaleResolver, LocaleChangeInterceptor parses both locale formats by default now. Since it does not need to render the locale, its languageTagCompliant property is not relevant anymore at all.
The parseLocale method in StringUtils validates the locale value now and turns an empty locale into null, compatible with parseLocaleString behavior and in particular aligned with web locale parsing needs.

Issue: SPR-16651
Introduces a configure method pattern for Supplier-style configuration and a common SingletonSupplier decorator for method reference suppliers. Also declares jcache.config and jcache.interceptor for non-null conventions.
Issue: SPR-17021
In order to allow Spring Framework applications running as GraalVM
native images, ReactiveAdapterRegistry should perform explicit class
checks instead of catching Throwable in order to avoid
UnsupportedFeatureError errors.
Issue: SPR-17000
Includes an efficient implementation of isEmpty(), not relying on a full entry count but rather backing out once a non-empty hash segment has been found.
