We now skip PersistentPropertyPath instances pointing to auditing properties for which the path contains a collection or map path segment as the PersistentPropertyAccessor currently cannot handle those. A more extensive fix for that will be put in place for Moore but requires more extensive API changes which we don't want to ship in a Lovelace maintenance release.

We now catch the MappingException produced by trying to set auditing property paths containing null intermediate segments and ignore those. A less expensive (non-Exception-based) approach is going to be introduced for Moore as it requires API changes to the property path setting APIs.

We now use StringUtils.hasLength(…) in the check whether to drop request elements from binding instead of ….hasText(…) as the latter drops blank strings so that's impossible to search for properties that contain a blank.
In Kotlin, it is idiomatic to deal with return value that could have or not a result with nullable types since they are natively supported by the language. This commit adds CrudRepository.findByIdOrNull(…) variant to CrudRepository#findById that returns T? instead of Optional<T>.

We now fall back to reflection-based PropertyAccessor/EntityInstantiator strategies when framework types are not visible by the entity's ClassLoader.
Typically, we use class generation to create and load PropertyAccessor and EntityInstantiator classes to bypass reflection. Generated types are injected into the ClassLoader that has loaded the actual entity. Generated classes implement framework types such as ObjectInstantiator and these interfaces must be visible to the ClassLoader that hosts the generated class. Some arrangements, such as OSGi isolate class repositories so the OSGi class loader cannot load our own types which prevents loading the generated class.

We now inspect all methods that match the wither method pattern (name, accepting a single argument) to find the most specific method returning the actual entity type.
Previously, we attempted to find a method only considering name and argument properties and not the return type. This lookup strategy could find a method returning the entity super type that isn't assignable to the entity type.

We now use ConcurrentHashMap as type instead of HashMap to properly synchronize concurrent updates to missing cache elements.
The previously used HashMap was not thread-safe so concurrent modifications resulted in ConcurrentModificationException.
