Summary

0002118: hessian serialization issue: ArrayList declared as Collection

Description

(rep by Daniel Spangler)

// Bean to be serialized as a parameter to the service below.
@Entity
@Table(name="patient")
public class Patient implements Serializable {
...
   @OneToMany(mappedBy="patient", fetch=FetchType.LAZY)
   private Collection<Order> orders = new ArrayList<Order>();

Serializing a Patient object to an EJB service as a parameter, causes the issue below.

// EJB service
@Stateless
@Local(OrderSubmissionService.class)
public class OrderSubmissionServiceBean implements OrderSubmissionService {

    // service with "Patient" as a parameter
    public Long createOrder(final Patient patient) throws ServiceException {
      ...
    }
}

In the Patient object the "orders" is an ArrayList and the target is java.util.Collection, which should work, but seems to be confusing Hessian for some reason.
