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.
Entities without an identifier previously an exception because the IsNewStrategyFactory wasn't able to determine a strategy even if there was no auditing to be applied in the first place.
We now eagerly check for auditability and skip the lookup for an IsNewStrategy completely in case that check returns false.

Extend AuditableBeanWrapper to allow access to the last modification date of a target object. Made AuditableBeanWrapperFactory an interface and renamed what’s been previously known under this name as DefaultAuditableBeanWrapperFactory.
The components previously relying on a MappingContext to lookup a PersistentEntity now use PersistentEntities to be able to back a collection of MappingContexts behind that and also avoid unmanaged types to be added to the MappingContext.
We now also register the JSR-310 and ThreeTen back-port converters with the ConversionService to be able to get and set auditing dates as these types.
To be able to customize the lookup of bean properties by persistent store we now expose a getPropertyAccessor(Object entity) method on PersistentEntity. It returns a PersistentPropertyAccessor which is basically an interface with a simplified API of BeanWrapper.
Reduced the plain BeanWrapper to not perform any type conversion to be able to drop the ConversionService dependency. To compensate for that we introduced a ConvertingPropertyAccessor that takes a ConversionService and delegates to a standard PersistentPropertyAccessor and applies conversions if necessary.
Refactored client APIs to use the PersistentPropertyAccessor instead of referring to BeanWrapper directly. Deprecated BeanWrapper.create(…) for removal in RC1.
Added a MappingAuditableBeanWrapperFactory to be able to use themapping metamodel to lookup annotations on persistent properties. This propagates into AuditingHandler and IsNewAwareAuditingHandler getting new constructors taking a MappingContext to set themselves up correctly. This will probably need store specific updates in the setup of the auditing infrastructure for namespace implementations and annotation based JavaConfig.
Introduced ….getPersistentProperty(Class<? extends Annotation> annotationType) on PersistentEntity to be able to access properties with a given annotation.
Updated SonarGraph architecture description and moved auditing related config classes into auditing.config package.
Cleaned up configuration setup. AuditingBeanDefinitionRegistrarSupport now exposes a getAuditingHandlerBeanName() method to determine the bean name to be used for the AuditingHandler.
The auditing subsystem now supports the usage of JDK 8 date time types when running on Spring 4.0.1 or better. To achieve that switched to use the DefaultFormattingConversionService which registers the relevant converters needed. We also modified the SPI CurrentDateTimeProvider to return a Calendar instance as it carries time-zone information to be able to convert the instance into time-zone based JDK 8 date/time types.
This also allows us to make the use of JodaTime optional and only rely on it in case of the usage of Auditable or any of the JodaTime types used in the annotation based scenario. Added support to set LocalDateTime as well.
Removed the unnecessary type arguments for AuditingHandler so that the setter taking an AuditorAware<T> can be successfully wired against implementations other than AuditorAware<Object> with Spring 4. The type argument was superfluous anyway as internally the type wasn't referred to and the handler is not used on a by-type basis.
Basic infrastructure for supporting annotation based auditing configuration.
Introduces AuditingBeanDefinitionRegistrarSupport for store specific auditing configuration enhancements. An AuditorAware instance is wired into the Auditing handler automatically if it's present in the ApplicationContext. The auditorAwareRef attribute of the enabling annotation can be used to disambiguate in case multiple AuditorAware instances are present in the configuration.

We're not manually converting the DateTime instance into the user field type but delegate to a ConversionService instance. This will allow us to automatically adhere to enhancements in conversion capabilities to the DefaultConversionService.
