Solutions

1. Provide a constructor on the persister class with the exact signature Hibernate expects (EntityBinding/PersistentClass, EntityMetamodel/Collection, PersistenceContext).
2. Make the constructor public or at least accessible to the persister factory.

When it happens

Trigger: Hibernate bootstrap fails to create a configured custom implementation class.

Common situations: A custom persister/factory/resolver class is missing, non-public, or lacks the required constructor.
