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.
