Cause (Documented platform behavior): Hibernate 7 validates the model more strictly; incompatible converters now error instead of being ignored.

Problem details
- Observed symptom
- SessionFactory/EntityManagerFactory fails to start after upgrade; previously the converter was silently ignored on those attributes.
- Context
- Product: Hibernate ORM Component: BasicValueBinder converter validation Operation: Bootstrapping a persistence unit with auto-applied or explicit AttributeConverters after upgrading to Hibernate 7 Affected versions: Hibernate ORM 7.0+ Environment: JVM Exception: org.hibernate.AnnotationException Packages: org.hibernate.orm:hibernate-core >=7.0 Trigger: An @Converter(autoApply=true) whose type matches an attribute that is @Id, @Version, @Enumerated, @Embedded, @Temporal or an association, or an explicit @Convert on such attributes.

Proposed fix: [Hibernate 7] AnnotationException "'AttributeConverter' not allowed for attribute '<name>' annotated '@jakarta.persistence.Id' (use '@Convert(disableConversion=true)' to suppress this er
Recommended action: Remove the explicit @Convert, or add @Convert(disableConversion=true) on the attribute to opt out of an auto-applied converter; review other 7.0 model validations (misplaced annotations, @Basic+@ManyToOne, generator mismatches).
