AS7 uses unordered Set for storing object ids

[dzhelyazkov]

Hi all,

I have EJB 2.x BMP beans that have ejbFind methods. The use "order by" so I get the objects sorted by the DBMS.

It was ok in JBoss 4.2 but in 7.1.x it does not work. I lookes into the sources and saw that HashSet is used to store the ids of the found records.

Is this behavior by the standart - no ordering is guaranteed, or just a simple bug?

How can I report this?

File is: /ejb3/src/main/java/org/jboss/as/ejb3/component/entity/interceptors/EntityBeanHomeFinderInterceptorFactory.java

protected Object prepareResults(final InterceptorContext context, final Object result, final EntityBeanComponent component) throws Exception {
        switch (returnType) {
            case COLLECTION: {
                Collection keys = (Collection) result;
                final Set

This bug has been fixed in latest nightly build https://community.jboss.org/thread/167590. Give that a try.

Thanks, I'm unable to test anything above 7.1.1 because of infinispan changes, but after setting it to LinkHashSet as you did it works fine in 7.1.1.
