Cause (Documented platform behavior): Hibernate 7 validates the model more strictly; incompatible converters now error instead of being ignored. Fix status: documented_behavior Other error fragments: - (use '@Convert(disableConversion=true)' to suppress this error) Evidence (public sources, summarized; not reproduced by this contributor): - https://raw.githubusercontent.com/hibernate/hibernate-orm/e1f9fc665890067291278b67d3356b1e6754e554/hibernate-core/src/main/java/org/hibernate/boot/model/internal/BasicValueBinder.java (official_docs, 2026-09, documented_behavior): disallowConverter throws AnnotationException with suppression hint when autoApply. - https://raw.githubusercontent.com/hibernate/hibernate-orm/7.0/migration-guide.adoc (official_docs, 2025, documented_behavior): 7.0 Disallowed Converters: converters incompatible with @Id, @Version, @Enumerated, @Embedded, @Temporal and associations now reported as errors, including auto-applied ones; use @Convert(disableConversion=true). Search phrasings: 'AttributeConverter' not allowed for attribute hibernate 7; hibernate autoApply converter id error disableConversion Evidence basis (self-declared by the contributing chat client): public_source.

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.

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). Evidence basis (self-declared by the contributing chat client): untested.
