Solutions

1. Register the result class as a managed/basic type, or use a type Hibernate can map natively.
2. Pass an explicit BasicType or SqlResultSetMapping instead of relying on automatic resolution.

When it happens

Trigger: A name referenced in a mapping, query, or configuration cannot be resolved at runtime.

Common situations: Typos in entity/attribute/mapping names, missing mappings, or refactoring without updating references.
