Consistent and efficient access to BeanDefinition argument values [SPR-16192]

[spring-issuemaster]

Juergen Hoeller opened SPR-16192 and commented

Starting with a nullability mismatch between AbstractBeanDefinition.getConstructorArgumentValues/getPropertyValues and its corresponding setters (which should get addressed for the Kotlin bean DSL), it turns out that all such access can be optimized through the introduction of hasConstructorArgumentValues/hasPropertyValues methods, never enforcing the creation of those holders objects unless actually necessary. The same applies to getMethodOverrides.
