With #20432 leading to yet another need for a Kotlin-specific parameter declaration check, let's take the opportunity to streamline our Kotlin support code: Specifically, we can unify the detection of Kotlin's optional parameters in MethodParameter.isOptional(), reduce BeanUtils.findPrimaryConstructor to Kotlin semantics (for reuse in AutowiredAnnotationBeanPostProcessor as well as data class construction), and finally introduce a common KotlinDetector delegate with an isKotlinType(Class) check.
Affects: 5.0 RC4
Issue Links:
#20232 Kotlin class instantiation with optional parameters and default values
#20402 Add support for Kotlin autowired constructor with optional parameters
#20432 Revisit handling of missing fields (without default values) for immutable data classes
#21825 GenericApplicationContext.registerBean should support non-default constructors
