Maintain iteration order for entity bean finders
------------------------------------------------
Key: AS7-4772
URL: https://issues.jboss.org/browse/AS7-4772
Project: Application Server 7
Issue Type: Bug
Components: EJB
Affects Versions: 7.1.1.Final, 7.1.2.Final (EAP)
Reporter: Mattias Nilsson Grip
Assignee: jaikiran pai
Labels: ejb2, find, interceptor, iterators, sorting
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
