Accessing fieldMappings on the interface Doctrine\Common\Persistence\Mapping\ClassMetadata suggest that you code against a concrete implementation. How about adding an instanceof check?

Are you sure $item->getId() of type Ramsey\Uuid\UuidInterface can be used in concatenation? Consider adding a __toString()-method.
