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.

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.

Prior to this commit, the lookup of types to be added as persistent entities for a given PersistentProperty used the actual property type which did not consider the association target type at all. Removed the usage of Optional for the entity type information and switched to use TypeInformation for the raw association target type so that it can be considered in ….getActualType().
We now throw MappingInstantiationException with a nested BeanInstantiationException in alignment to ReflectionEntityInstantiator when attempting to create a new instance of an abstract class.
Closes#2348.
We now detect the component type of jMolecules' Association as association target type in AbstractPersistentProperty. AnnotationBasedPersistentProperty keeps the lookup of the explicit @Reference around but falls back to the Association analysis for that.
@Reference is now only considered by AnnotationBasedPersistentProperty. It was previously also (erroneously) considered by AbstractPersistentProperty.
It was also changed to return `null` in case no association target type could be looked up instead of returning the sole property's type in case that is an entity. This was done to satisfy the behavior documented on the interface but also to avoid the call to isEntity() during the calculation which might use association information in turn and thus lead to a stack overflow. Reworded the contract of PersistentProperty.getAssociationTargetType() to emphasize the symmetry with ….isAssociation() in implementation classes.
Closes: #2344.
We now support composed annotation that are annotated with `@Value`. we also expose MergedAnnotations through PreferredConstructor.Parameter for further use by store modules that want to inspect constructor argument annotations.

We now resolve only the raw class when checking if a primary constructor argument is assignable to method parameters of the synthetic copy method.
Previously we used ResolvableType's assignability check which considered generic type arguments. As the type resolution between the KType and copy method type is not symmetric, the check only succeeded in cases where both types could be resolved to the same type/assignable type. Using projections or Any caused asymmetric resolution and therefor the assignability check returned non-assignable.
Closes#2336.
We now resolve the copy method for Kotlin data classes that match the primary constructor. Previously, copy method resolution could find a secondary copy method as we didn't check for the primary constructor structure (parameter names and types).
Closes#2324.
We no recognize properties of type org.jmolecules.ddd.types.Association as associations in our PersistentProperty model.
Also, we now register JMolecules Converter implementations for Association and Identifier in CustomConversions so that they can persisted like their embedded primitive value out of the box.
Fixes#2315.

In oder to preserve contextual information the PersistentPropertyPathFactory now obtains EntityInformation for properties from the MappingContext via their PersistentProperty representation instead of plain the TypeInformation as the former contains more information about the actual type and signatures.
