Issue Type: Bug Affects Versions: 5.4.15 Assignee: Vlad Mihalcea ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%3Af5e8c0d3-3aae-4bb4-a4e1-25463d60d232 ) 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%3Af5e8c0d3-3aae-4bb4-a4e1-25463d60d232 )

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.
