Vlad Mihalcea ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) *updated* an issue Hibernate ORM ( https://hibernate.atlassian.net/browse/HHH?atlOrigin=eyJpIjoiYmVmN2M4MWIy... ) / Bug ( https://hibernate.atlassian.net/browse/HHH-14000?atlOrigin=eyJpIjoiYmVmN2... ) HHH-14000 ( https://hibernate.atlassian.net/browse/HHH-14000?atlOrigin=eyJpIjoiYmVmN2... ) Allow a custom Type that was registered via Type Contributors to be resolved by its class, not just its name ( https://hibernate.atlassian.net/browse/HHH-14000?atlOrigin=eyJpIjoiYmVmN2... ) Change By: Vlad Mihalcea ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) Considering we have a custom Type we register like this: {noformat}@Override protected void addConfigOptions(Map options) { options.put( EntityManagerFactoryBuilderImpl.METADATA_BUILDER_CONTRIBUTOR, (MetadataBuilderContributor) metadataBuilder -> metadataBuilder.applyTypes( (typeContributions, serviceRegistry) -> { typeContributions.contributeType( ArrayType.INSTANCE ); } )); }{noformat} When calling the following query: {code:java}List<CorporateUserDTO> emails = entityManager.createNativeQuery( "select " + " u.userName as userName, " + " u.emailAddresses as emailAddresses " + "from CorporateUser u " + "where u.userName = :name", "CorporateUserDTO" ) .setParameter( "name", "Vlad" ) .getResultList();{code} Where the {{CorporateUserDTO}} result set mapping is mapped like this: {code:java}@SqlResultSetMapping( name = "CorporateUserDTO", classes = @ConstructorResult( targetClass = CorporateUserDTO.class, columns = { @ColumnResult(name = "userName"), @ColumnResult(name = "emailAddresses", type = Array.class), } ) ){code} The following exception is thrown: {noformat}javax.persistence.PersistenceException: org.hibernate.type.SerializationException: could not deserialize at org.hibernate.internal.ExceptionConverterImpl.convert(ExceptionConverterImpl.java:154) at org.hibernate.query.internal.AbstractProducedQuery.list(AbstractProducedQuery.java:1542) at org.hibernate.query.Query.getResultList(Query.java:165) at org.hibernate.test.type.contributor.ArrayTypeContributorTest.lambda$testNativeSQL$5(ArrayTypeContributorTest.java:99){noformat} That’s because the {{Array}}property is resolved by {{SerializableType}} instead of {{ArrayType}}.
