The code is changed *from* : @Type(type = "jsonb") @Column(columnDefinition = "jsonb") public ServiceTaskCallback serviceTaskCallback; *to* @Type(io.hypersistence.utils.hibernate.type.json.JsonBinaryType.class) @Column(columnDefinition = "jsonb") public ServiceTaskCallback serviceTaskCallback; Similar problem is reported by this stackoverflow ( https://stackoverflow.com/questions/74928307/hibernate-upgrade-to-v6-spri... ) issue. Here's the *repro* code: package com.example.demo; import java.util.*; import jakarta.persistence.*; import org.hibernate.annotations.Type; import io.hypersistence.utils.hibernate.type.json.JsonBinaryType; public class DemoApplication2 { public static void main( String [] args) { // This fails...

NOTE ! === // If this is uncommented and below fragment (which is the SAME) is commented then it works. // @Type(JsonBinaryType.class) // @Column(columnDefinition = "jsonb" ) // public ServiceTaskCallback serviceTaskCallback; } @MappedSuperclass public static class TaskServiceDocument<E extends Enum<E>> extends MultiTenantDocument { // === ! NOTE ! === // This is the problematic field. // Same snippet defined above works. @Type(JsonBinaryType.class) @Column(columnDefinition = "jsonb" ) public ServiceTaskCallback serviceTaskCallback; } // Complains: did not implement BasicType nor UserType // It worked with Hibernate 5 public static class ServiceTaskCallback { public String serviceSelfLink; } @Entity public static class GenericTaskState extends TaskServiceDocument<GenericTaskState.SubStage> { public enum SubStage { CREATED } public String taskId; } } Here’s persistence.xml: <persistence xmlns= "http://java.sun.com/xml/ns/persistence" xmlns:xsi = "http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation= "http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd" version= "2.0" > <persistence-unit name= "my-persistence-unit" > <provider> org.hibernate.jpa.HibernatePersistenceProvider </provider> <properties> <property name= "jakarta.persistence.jdbc.driver" value= "org.postgresql.Driver" /> <property name= "jakarta.persistence.jdbc.url" value= "jdbc:postgresql://localhost:5432/postgres" /> <property name= "jakarta.persistence.jdbc.user" value= "postgres" /> <property name= "jakarta.persistence.jdbc.password" value= "password" /> </properties> </persistence-unit> </persistence> And here’s the full stack trace: 16:41:00.930 [main] DEBUG org.hibernate.internal.SessionFactoryImpl - Eating error closing SF on failed attempt to start it Exception in thread "main" jakarta.persistence.PersistenceException: [PersistenceUnit: my-persistence-unit] Unable to build Hibernate SessionFactory at org.hibernate.jpa.boot.internal.EntityManagerFactoryBuilderImpl.persistenceException(EntityManagerFactoryBuilderImpl.java:1509) at org.hibernate.jpa.boot.internal.EntityManagerFactoryBuilderImpl.build(EntityManagerFactoryBuilderImpl.java:1430) at org.hibernate.jpa.HibernatePersistenceProvider.createEntityManagerFactory(HibernatePersistenceProvider.java:55) at jakarta.persistence.Persistence.createEntityManagerFactory(Persistence.java:80) at jakarta.persistence.Persistence.createEntityManagerFactory(Persistence.java:55) at com.example.demo.DemoApplication.main(DemoApplication.java:28) Caused by: java.lang.IllegalArgumentException: Named type [class com.example.demo.DemoApplication$ServiceTaskCallback] did not implement BasicType nor UserType at org.hibernate.boot.model.TypeDefinition.createResolution(TypeDefinition.java:271) at org.hibernate.boot.model.TypeDefinition.createResolution(TypeDefinition.java:121) at org.hibernate.boot.model.TypeDefinition.resolve(TypeDefinition.java:106) at org.hibernate.mapping.BasicValue.interpretExplicitlyNamedType(BasicValue.java:671) at org.hibernate.mapping.BasicValue.buildResolution(BasicValue.java:353) at org.hibernate.mapping.BasicValue.resolve(BasicValue.java:315) at org.hibernate.mapping.BasicValue.getType(BasicValue.java:293) at org.hibernate.metamodel.internal.AttributeFactory.determineAttributeMetadata(AttributeFactory.java:375) at org.hibernate.metamodel.internal.AttributeFactory.buildAttribute(AttributeFactory.java:111) at org.hibernate.metamodel.internal.AttributeFactory.buildAttribute(AttributeFactory.java:96) at org.hibernate.metamodel.internal.MetadataContext.wrapUp(MetadataContext.java:331) at org.hibernate.metamodel.model.domain.internal.JpaMetamodelImpl.processJpa(JpaMetamodelImpl.java:504) at org.hibernate.metamodel.model.domain.internal.MappingMetamodelImpl.finishInitialization(MappingMetamodelImpl.java:244) at org.hibernate.metamodel.internal.RuntimeMetamodelsImpl.finishInitialization(RuntimeMetamodelsImpl.java:60) at org.hibernate.internal.SessionFactoryImpl.<init>(SessionFactoryImpl.java:311) at org.hibernate.boot.internal.SessionFactoryBuilderImpl.build(SessionFactoryBuilderImpl.java:415) at org.hibernate.jpa.boot.internal.EntityManagerFactoryBuilderImpl.build(EntityManagerFactoryBuilderImpl.java:1425) ... 4 more ( https://hibernate.atlassian.net/browse/HHH-16122#add-comment?atlOrigin=ey... ) Add Comment ( https://hibernate.atlassian.net/browse/HHH-16122#add-comment?atlOrigin=ey... ) Get Jira notifications on your phone!
