Vlad Mihalcea ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) *created* an issue Hibernate ORM ( https://hibernate.atlassian.net/browse/HHH?atlOrigin=eyJpIjoiZjA2OTdkM2M3... ) / Bug ( https://hibernate.atlassian.net/browse/HHH-14000?atlOrigin=eyJpIjoiZjA2OT... ) HHH-14000 ( https://hibernate.atlassian.net/browse/HHH-14000?atlOrigin=eyJpIjoiZjA2OT... ) A "Could not locate appropriate constructor on class" is thrown when calling JPA createNativeQuery(String sqlString, String resultSetMapping) ( https://hibernate.atlassian.net/browse/HHH-14000?atlOrigin=eyJpIjoiZjA2OT... ) Issue Type: Bug Affects Versions: 5.4.15 Assignee: Vlad Mihalcea ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) Components: hibernate-core Created: 04/May/2020 03:50 AM Fix Versions: 5.4.16 Priority: Major Reporter: Vlad Mihalcea ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) When calling the following query: 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(); Where the emailAddresses uses a custom Typ and the result set mapping is mapped like this: @SqlResultSetMapping( name = "CorporateUserDTO" , classes = @ConstructorResult( targetClass = CorporateUserDTO.class, columns = { @ColumnResult(name = "userName" ), @ColumnResult(name = "emailAddresses" , type = Array.class), } ) ) The following exception is thrown: java.lang.IllegalArgumentException: Could not locate appropriate constructor on class : org.hibernate.test.type.contributor.ArrayTypeContributorTest$CorporateUserDTO at org.hibernate.loader.custom.ConstructorResultColumnProcessor.resolveConstructor(ConstructorResultColumnProcessor.java:92) at org.hibernate.loader.custom.ConstructorResultColumnProcessor.performDiscovery(ConstructorResultColumnProcessor.java:45) at org.hibernate.loader.custom.CustomLoader.autoDiscoverTypes(CustomLoader.java:494) at org.hibernate.loader.Loader.processResultSet(Loader.java:2338) It looks like the Constructor is resolved using the Hibernate Type instead of the actual Java Type.
