Looking up a PersistentEntity via ….getPersistentEntity(…) applies some massaging of the given type as it could be a proxy type created for a user type. That wrangling was not applied in ….hasPersistentEntity(…) which resulted in a call to that method with a proxy type yielding false although it shouldn't if we already have a PersistentEntity available for the corresponding user type.
We now explicitly lookup the entity by original type and, if it's not the user type itself, try to look up the entity for the latter.
Fixes#2589.
We now consider IllegalArgumentException as marker for incompatible lambda payload that was introduced with Java 18's reflection rewrite that uses method handles internally.
Closes#2583
Increase visibility of converter builders.
Refine generics naming towards DV/SV instead of A/B to easier identify store-native values and domains-specific values in the API. Refactor PropertyValueConversions.hasValueConverter into a non-default method.
Tweak documentation.
See #1484
Original pull request: #2566.
Introduce a builder API to register PropertyValueConverters using simple (Bi)Functions. Additional methods on ValueConversionContext to enable advanced use cases in converter implementation. Tweak generics of VCC to be able to expose store-specific PersistentProperty implementations via the context.

Original pull request: #2566.
Move to @PersistenceCreator as canonical annotation to explicitly express constructors and methods to be used to create domain object instances from persistence operations. Removed @FactoryMethod as it's not needed anymore. @PersistenceConstructor is now deprecated.
Renamed EntityCreatorMetadata(Support|Discoverer) to InstanceCreatorMetadata(Support|Discoverer) to avoid further manifestation of the notion of an entity in the metamodel as it's not used to only handle entities.
Issue #2476.
Use var instead of explicit local types where applicable. Use pattern variable instead instanceof and cast. Prefer loops and nullable types over Stream and Optional. Convert classes to records where applicable.
See #2465
A few further tweaks: ClassTypeInformation now never unwraps the user type to consistently work with the type originally presented in the lookup. That allows us to get rid of the custom equals(…)/hashCode() methods and removes the need to deal with original and user type in the same CTI instance.
The augmented caching of PersistentEntities in AbstractMappingContext now primarily happens in doAddPersistentEntity(…). We still need to implement a cache manipulation for the case that a user type has caused the creation of a PersistentEntity first and we see a lookup for the proxy type later. Before actually processing the TypeInformation we now try to lookup an already existing PersistentEntity for the user type and augment the cache if one was found.

Remove isProxyTypeInformation from TypeInformation. Use computeIfAbsent to fall back to user type information when attempting to add a entity to the MappingContext.
See #2485
Original pull request: #2486.
This commit makes sure to only create a PersistentEntity for an actual user type. Therefore ClassTypeInformation now considers the given type and not only the user one for both equals and hashcode. This makes sure we can distinguish TypeInformation for a proxy from the one of a user class.
The AbstractMapping context will take care of unpacking proxied types and registering the created entity for both the user as well as the proxy type information.
Prior to this commit build time generated proxy instances would have been able to pollute the context depending on the order they had been served by the initial entity set.

We now reuse generated ObjectInstantiator classes instead of attempting to redefine classes with the same name. Redefinition leads to LinkageError and thus to the use of reflection-based instantiators and an increased allocation rate due to the failed attempt of class redeclaration.
Closes: #2446.
Extract adding the actual entity to the MappingContext into its own method along with error handling spanning the entire entity initialization process.
See #2329
Original pull request: #2367.
When an error happens inside the AbstractMappingContext, the caching sometimes gets corrupted. That's because some exceptions are caught, others are not. Instead, the error handling that clears out the cache needs to be shifted up one level, resulting in a simpler code block.

This causes us to inspect the most concrete type we can find from a property declaration that might be overridden using an annotation.
Closes: #2409
Original Pull Request: #2410
We now name methods returning a TypeInformation<?> …TypeInformation() and ones that return Class<?> …Type(). In case of both flavors provided, overloads should move to the TypeInformation-based variant as the other one simply resolves ….getType() on the returned value.
Closes: #2408

Unified the calculations made for entityTypeInformation and entityTypes in AbstractPersistentProperty. This avoids both calculations getting out of sync. Also we avoid premature calculation abortions if SimpleTypeHolder.isSimpleType(…) returns true for the raw property type. The latter has caused issues for collection properties in Spring Data KeyValue which considers everything in java.util a simple type.

Reduce TypeDiscoverer.isNullableWrapper method visibility to private to avoid exposure in preparation for wider value type support.

We now validate declared annotations by pre-processing these through AnnotatedElementUtils to ensure a proper comparison. Previously, we compared annotation in their declared form (AnnotatedElement.getAnnotations()) with merged annotations which could fail due to aliasing effects of merged annotations.
Closes#2368.
Previously, we tried to invoke the copy(…) method on all Kotlin classes whereas the copy(…) method is only specific to Kotlin data classes.
