A failure to resolve a property path into a PersistentPropertyPath now causes an InvalidPropertyPath exception being thrown. It captures the context of the failure like the resolved path, the offending segment. Added getPersistentPropertyPath(InvalidPropertyPath) that resolves the resolvable part for further use downstream.
Added null-checking assertions to AbstractMappingContext.getPersistentPropertyPath(…) variants. Improved DefaultPersistentPropertyPath to be able to append properties while building and to allow representing an empty path.
