[hibernate-issues] [Hibernate-JIRA] Created: (ANN-668) Method in entity with return type of ArrayList<Object[]> causes failure to build session factory
Method in entity with return type of ArrayList<Object[]> causes failure to build
session factory
------------------------------------------------------------------------------------------------
Key: ANN-668
URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-668
Project: Hibernate Annotations
Issue Type: Bug
Affects Versions: 3.3.0.ga
Environment: Hibernate 3.2.X, no database needed (happens during factory build
before connecting to db)
Reporter: Clint Popetz
Attachments: propertyTypeExtractorBug.tar.gz
The following source:
@javax.persistence.Entity
public class TestEntity {
@javax.persistence.Id
public int Id;
public java.util.ArrayList<Object[]> badMethod() { return null; }
public static void main(String args[]) {
new
org.hibernate.cfg.AnnotationConfiguration().addAnnotatedClass(TestEntity
.class).configure().buildSessionFactory();
}
}
will cause:
java.lang.IllegalArgumentException: No PropertyTypeExtractor available for type void

Changing the return type to List<Object[]> avoids the bug.
Attached is a tgz of an ant-buildable project; typing "ant run" will illustrate
the bug.
