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

Add Nullable annotation to ParsingUtils, Sort.Order and PropertyValueProvider.
Add getRequiredAnnotation(…) to PersistentEntity and PersistentProperty to provide methods returning required, non-null annotations.
Moved PreferredConstructorDiscoverers into PreferredConstructorDiscoverer to hide more API. Renamed ClassGeneratingKotlinEntityInstantiator to KotlinClassGeneratingEntityInstantiator.
Use org.springframework.util.Assert instead of com.mysema.commons.lang.Assert.

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)
}

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.
We now use CGLibs ReflectUtils.defineClass(…) to inject classes into the entity's class loader instead of our own code. ReflectUtils itself discovers whether the class loader is encapsulated and falls back to Unsafe for class definition. We no longer require our own code so the evil class was removed.

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(…).

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.
Deprecated the additional method in favor if a lookup via MappingContext.getPersistentPropertyPath(PropertyPath) using the resolvable PropertyPath exposed by InvalidPersistentPropertyPath.
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.
Refactored type alias detection invocation in BasicPersistentEntity into separate method and avoid the factory method Alias.ofOptional(…) so that it can be removed.
Remove javadoc params without documentation. Reorder methods in the order they are called. Rename arePropertyHashCodesUnique to hasUniquePropertyHashCodes. Add author tag. Formatting.

Refactored all the checks done to check if ClassGeneratingPropertyAccessorFactory works into separate methods, so the body of isSupported becomes nice and readable.
Original pull request: #224.
ClassGeneratingPropertyAccessorFactory does not work with Java 9 (encapsulated modules, without --permit-illegal-access), because making ClassLoader.defineClass accessible fails.
Therefore this change moves call to setAccessible to the check that ensures availability of the method so isSupported(…) returns false.
Original pull request: #224.
We now eagerly check the accessibility of the defineClass(…) method on the class loader to be used for a PersistentEntity. This will then cause the clients to use a different PropertyAccessorFactory (as things stand today: the one using reflection) and not fail to create the class later on.
Extracted CustomConversions — whose code has largely been duplicated between the MongoDB, Couchbase and Cassandra modules — into Spring Data Commons. Store-specific extensions can now be contributed via a StoreConversions value type that carries both, store-specific default converters as well as a store-specific SimpleTypeHolder to augment the default list of simple types.
Removed SimpleTypeHolders public default constructor in favour of a protected one and a static DEFAULT instance for plain references.
Original pull request: #210.
The new method allows to look up identifiers and immediately fail in the case of absence. Introduced the method as default method but also a new base type TargetAwareIdentifierAccessor to throw an exception with more context, i.e. the actual target bean we try to look up the identifier on.
Moved getRequired…(…) methods from implementations into interfaces so that implementations inherit them by default.
Expanded generics declaration in PersistentEntities so that PerisistentProperty instances can be properly access from the PersistentEntity instances returned.
Make use of lambdas and method references though out the codebase. Remove no longer required generic type parameters.
Additionally remove unused imports and replace single element list initialization with dedicated singletonList.
Use Assertion overloads taking Supplier for dynamic assertion error messages.
Fix hotspot in constructor lookup - in particular the propertyAccessorClass.getConstructors() call.
Additionally fix another minor issue in assertion message creation.
