Restored original singleton-only adaptInnerBeanName behavior, avoiding endless unique name calculation for every single prototype instance. Non-named inner BeanDefinition objects now suffixed with an identity hex code analogous to non-named XML bean definitions, largely avoiding naming collisions to begin with. After SPR-11246, post-processors can deal with unstable classes per bean name, so occasional collisions aren't a hard problem anymore.
Issue: SPR-11545
(cherry picked from commit 5308b3e)
Prior to this commit, the inclusion of the 'overloaded' flag in the
implementations of equals() and hashCode() in MethodOverride could lead
to adverse effects in the outcome of equals() in AbstractBeanDefinition.
For example, given two bean definitions A and B that represent the
exact same bean definition metadata for a bean that relies on method
injection, if A has been validated and B has not, then A.equals(B) will
potentially return false, which is not acceptable behavior.
This commit addresses this issue by removing the 'overloaded' flag from
the implementations of equals() and hashCode() for MethodOverride.

This in particular allows for specifying "spring.getenv.ignore" and "spring.beaninfo.ignore" in a local way within the application, in case that JVM-level system properties are locked.

This allows us to avoid early initialization of footprint-heavy ConcurrentHashMaps, and reuses the existing postProcessingLock which will typically be active already when registerExternallyManaged* calls come in from the bean factory's post-processing phase.

(cherry picked from commit a599b57)
Specifically, read and write methods are allowed to express property types with superclass/subclass relationships in both directions now.

Our per-bean caching in AutowiredAnnotationBeanPostProcessor and co relies on unique bean names, so this change fixes potential cache mismatch problems occuring there.
Issue: SPR-11131
(cherry picked from commit 242ecdc)
Since @Bean methods are never used with externally specified constructor argument values but rather just with autowiring, the non-lenient constructor resolution mode is appropriate in case of an overloaded @Bean method, not performing any type difference weight checks. This change includes a refinement of Spring's existing non-lenient constructor resolution (which needs to be explicitly turned on and is therefore not well tested), narrowing the conditions for the ambiguity check (only in case of the same number of arguments and not for overridden methods).
Issue: SPR-10988
(cherry picked from commit b093b84)
Update TypeConverterDelegate to bypass conversion when the target type
is Object.class. Prior to this commit converting a single element array
to an Object would result in the element being returned, rather than
the array itself.
Issue: SPR-10996
(cherry picked from commit c9aace4d)
Also using ClassUtils.forName in AutowireUtils now in order to accept all common class name formats.
