BeanInstantiationException with @DynamicLabels and multiple levels of inheritance #2529
Description
SDN 6.2.4 is unable to instantiate nodes with multiple levels of inheritance and a non-empty @DynamicLabels field.
I have an example repo but here is a summary of the problem.
For example, say you have a super class
@Getter @Node public abstract class Animal { @DynamicLabels private Set<String> labels = new TreeSet<>(); } A sub class
@Node public abstract class Feline extends Animal { } And a sub class of the sub class
@Node public class Cat extends Feline { } You can query for instances of the Cat sub class only if they do not have a dynamic label
Cat cat1 = new Cat(); animalRepository.save(cat1); Cat cat2 = new Cat(); cat2.getLabels().add("Orange"); animalRepository.save(cat2); Cat found1 = (Cat) animalRepository.findById(cat1.getId()).get(); // this is fine Cat found2 = (Cat) animalRepository.findById(cat2.getId()).get(); // BeanInstantiationException The second query fails if the Feline sub class is abstract or concrete, though the exception is different.
This example worked correctly in SDN 6.2.1 but it fails with SDN 6.2.4.
