Solutions

1. Ensure the Interceptor class has a public no-arg constructor (or is supplied via a SessionFactory-scoped interceptor instance).
2. Check the interceptor class is on the classpath and instantiable (not abstract/interface).
3. Supply the interceptor instance programmatically via SessionFactoryOptions/Session.openSession(Interceptor) instead of by class name.

When it happens

Trigger: Hibernate cannot create the configured stateless SessionFactory Interceptor.

Common situations: hibernate.session_factory.stateless_interceptor naming a class that is missing or cannot be instantiated.
