     [ https://issues.jboss.org/browse/AS7-4772?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

jaikiran pai updated AS7-4772:
------------------------------

    Issue Type: Bug  (was: Feature Request)

Changing this to a bug since the current behaviour violates the ORDER BY clause that might be present in the application specific EJB QL.

> 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.
