             Summary: Maintain iteration order for entity bean finders
                 Key: AS7-4772
                 URL: https://issues.jboss.org/browse/AS7-4772
             Project: Application Server 7
          Issue Type: Feature Request
          Components: EJB
    Affects Versions: 7.1.1.Final
            Reporter: Mattias Nilsson
            Assignee: jaikiran pai


In previous JBoss AS versions (at least in JBoss AS 4.x) if a finder method in an EJB 2.x entity bean returned a collection or enumeration of primary keys in a specific order, the client would receive a collection or enumeration of entities with the same iteration order.

In JBoss AS 7, the entity bean home interceptor uses a HashSet when producing the collection of entities. This means iteration order is lost and clients receive the entities in random order.

As a convenience and as a backward compatibility for users migrating from previous JBoss versions, could you consider replacing java.util.HashSet with java.util.LinkedHashSet in org.jboss.as.ejb3.component.entity.interceptors.EntityBeanHomeFinderInterceptorFactory? I would be happy to provide a test case and a pull request with this change.

Regards,
Mattias
