We now only inspect regular Kotlin classes with inspection to adapt Kotlin-specific behavior. Multipart-, synthetic and unknown classes are not supported. In such cases we fall back to the JVM reflection mechanism.
Non-regular classes are typically synthetic stubs, lambdas and SAM conversion which do not represent typical domain objects but rather technical bridge code.

The new name currently delegates to old version, so classes only implementing the old method still work. Old name is deprecated.

We now validate query method invocations to check method parameters whether they accept null values and reject execution if null values are not supported. We derive nullability support from repository interfaces declared using Kotlin and Spring's NonNullApi/Nullable annotations.
We also check whether a query method can return null. If a query method returns null which isn't supposed to do so, then we throw EmptyResultDataAccessException to prevent null return values.
interface UserRepository extends Repository<User, String> {
List<User> findByLastname(@Nullable String firstname);
@Nullable
User findByFirstnameAndLastname(String firstname, String lastname);
}
interface UserRepository : Repository<User, String> {
fun findByLastname(username: String?): List<User>
fun findByFirstnameAndLastname(firstname: String, lastname: String): User?
}

We now allow users to use our own Streamable interface as query method return types to easily invoke ….stream() on everything that returns an Iterable using non-parallel streaming by default.
AbstractAggregateRoot is now generified to be able to use its concrete type on methods returning an instance of itself. Added new methods andEvent(…) and andEventsFrom(…) to easily transfer events from another aggregate instance. Added unit tests for fundamental functionality of the base class.
We now prefer to inspect the arguments handed to save(…) methods over inspecting the return value as the invocation of the actual method is free to exchange the instance handed into it and return a completely new one with the events contained in the parameter completely wiped.
We're now trying to look up a uniquely available ObjectMapper instance from the application context falling back to a simple new instance in case none can be found.
We now forward method parameters of methods on projection interfaces to the expression evaluation. The parameters are exposed via an array named "args".
Add Nullable annotation to ParsingUtils, Sort.Order and PropertyValueProvider.
Add getRequiredAnnotation(…) to PersistentEntity and PersistentProperty to provide methods returning required, non-null annotations.
We filter interfaces annotated with @NoRepositoryBean from fragment interface candidates and not longer scan for implementations of these.
Extending a base repository usually requires an interface which is used as base interface instead of Repository/CrudRepository in user repositories. If the naming scheme of the extended interface and the implementation fits to fragment interfaces, then we previously registered the class additionally as fragment implementation. The bean registration caused container startup failures because of unsatisfied dependencies or would shadow the base repository implementation.

We now discover Kotlin constructors and apply parameter defaulting to allow construction of immutable value objects. Constructor discovery uses primary constructors by default and considers PersistenceConstructor annotations.
KotlinClassGeneratingEntityInstantiator can instantiate Kotlin classes with default parameters by resolving the synthetic constructor. Null values translate to parameter defaults.
class Person(val firstname: String = "Walter") {
}
class Address(val street: String, val city: String) {
@PersistenceConstructor
constructor(street: String = "Unknown", city: String = "Unknown", country: String) : this(street, city)
}

Path expressions are now evaluated one by one with the first one actually available in the payload being used for value lookup. Also tweaked the default behavior to return null in case of an single, invalid path.
We're now favoring the generic TypeInformation over trying to resolve the property type via field or PropertyDescriptor as only the former does proper generic type resolution.
Type specialization - i.e. enrichment of a raw type with a current generic context - is now only done if the current type is not yet resolved completely. This allows wildcarded target references to just fall back to the type to specialize, which will then by definition carry more generics information than the one to be specialized.
Revert the merging of a parent type's type variable map and only apply the locally available declared generics in case of parameterized types. Moved that augmentation into ParameterizedTypeInformation.
XmlBeam 1.4.11 accidentally removed ProjectionFactory as public interface. Adapted our HttpMessageConverter implementation to make sure we still work on those versions.

Marked all packages with Spring Frameworks @NonNullApi. Added Spring's @Nullable to methods, parameters and fields that take or produce null values. Adapted using code to make sure the IDE can evaluate the null flow properly. Fixed Javadoc in places where an invalid null handling policy was advertised. Strengthened null requirements for types that expose null-instances.
Removed null handling from converters for JodaTime and ThreeTenBP. Introduced factory methods Page.empty() and Page.empty(Pageable). Introduced default methods getRequiredGetter(), …Setter() and …Field() on PersistentProperty to allow non-nullable lookups of members. The same for TypeInformation.getrequiredActualType(), …SuperTypeInformation().
Tweaked PersistentPropertyCreator.addPropertiesForRemainingDescriptors() to filter unsuitable PropertyDescriptors before actually trying to create a Property instance from them as the new stronger nullability requirements would cause exceptions downstream.
Lazy.get() now expects a non-null return value. Clients being able to cope with null need to call ….orElse(…).

If you previously asked ProxyProjectionFactory for a proxy of an interface which the target instance already implements, it created a proxy although it could've returned the instance as is. It's now actually doing that avoiding superfluous proxy creation.
RepositoryFactoryBeanSupport.getRepositoryInformation() previously didn't consider any store-specific compositions (incl. store-specific fragments like the Querydsl support) as it just handed a fragment with the custom implementation to RepositoryFactorySupport.
This is now fixed by improving the API in RepositoryFactorySupport which now exposes a getRepositoryInformation(RepositoryMetadata, RepositoryFragments) which creates a fresh RepositoryComposition from the given RepositoryMetadata. Intermediate setup methods are still kept around but private as RepositoryFactorySupport.getRepository(…) still needs to forward the base RepositoryComposition to method interceptors for query result mapping.
As the calculation of a PersistentPropertyPath instances is rather expensive and they're heavily used in downstream mapping operations (e.g. query and fields mapping in MongoDB) we now cache the instances created per base type and property path.
Previously, RepositoryBeanNameGenerator applied the custom bean name lookup if the BeanDefinition given was not a ScannedGenericBeanDefinition. That in turn had been the case for custom implementation classes that were obtained through classpath scanning. With Spring 5 an index file can be used by the scanner, which in turn will cause AnnotatedGenericBeanDefinition instances being returned. That caused the code path to lookup the first constructor argument to kick in (usually used to obtain the repository interface from repository factory beans) and cause a NullPointerException.
We now forward AnnotatedBeanDefinitions as is and only apply the custom lookup for everything else, i.e. the bean definitions used for the factories.
Re-enabled test cases for handling of different date/time APIs in auditing. Tweaked the lookup of the last modified value to try to convert to LocalDateTime as well in case it's a subtype of the type requested. In combination with two newly introduced converters for local date type times in JodaTime and ThreeTenBP, this allows us to still convert legacy JodaTime and ThreeTenBP types to be used as well.
We now keep instances of ReturnedType around to avoid the repeated reflection inspection for constructor and parameter name detection for class types and projection information for interfaces.
Removed the deprecated implementation of ResourceLoaderAware in favor of BeanClassLoaderAware. Removed deprecated ProjectionFactory.getInputProperties() in favor of ….getProjectionInformation(). Removed the Java conditional to add a MethodInterceptor for default methods. Adapted test cases.
Introduced new ExampleMatcherAccessor in data.support in favor of the now deprecated one in data.repository.core to avoid a dependency into the repositories subsystem to work with examples in general.
Added Degraph based test in order to avoid future cyclic package dependency violations.

We now use a marker interface to store cache hits for conversion targets without requesting a conversion target in the conversion query. The dedicated marker type has an individual cache view and does not interfere with other types.
Previously we used Object as cache key which caused false positives due to assignability checks. If an earlier conversion query with a requested target type yielded a hit (e.g. negative hit), subsequent queries without a target type received the same answer. This might happen although the non-cached answer would return a different result.
Move MappingException from o.s.d.mapping.model to o.s.d.mapping package and use it for getRequired* methods in MappingContext instead of throwing IllegalArgumentException. Further on we’ve consolidated usage of IllegalArgumentException and IllegalStateException. Along that IllegalMappingException was removed in favor or MappingException.
BasicPersistentEntity now looks up all properties by annotation instead of just returning the first one found. We’ve kept the original methods behavior and updated the comment as well as introduced getPersistentProperties returning all matching properties.
We now override ClassPathScanningCandidateComponentProvider's getRegistry() to make sure custom conditions on repository candidates can use the currently available BeanDefinitionRegistry in their implementations. To achieve that we forward the BeanDefinitionRegistry at hand through the configuration infrastructure (both XML and annotation side of things).
Switched to use Optional<Object> to make nullability explicit. Keep the original ….convert(…) method around as deprecated default method so that clients can be migrated gradually.
We now use specified date formats for converting various date types to Strings and comparing them.
Before, in some cases toString() was used which strips trailing zeros, causing sporadic failures.
JDK9 changed the behaviour of Date related toString methods, making tests fail all the time.
Therefore this fix is required for executing tests with JDK9.

Changed RepositoryConfiguration to return Streamable over Iterable. A couple of code reorganizations, suppression of raw type. Turned abstract helper classes into interfaces where possible. A couple of typos in JavaDoc.

We now use RepositoryComposition as backing implementation for repository method calls to implementations. We now scan for repository fragments during the repository configuration phase. Fragment implementation candidates derive from the repository interface declaration, specifically the declared interfaces and their order. We scan the class path during fragment scan for each interface and add discovered fragments to the repository composition. The name of the implementation is derived from the simple name of the interface and the implementation suffix. Qualified fragments are top-level interface declarations that are not annotated with NoRepositoryBean. Inherited interfaces are not considered as fragment candidates.
We create a RepositoryComposition from the discovered fragments in the order of interface declaration in the repository interface and supply the composition to the actual repository creation.
