org.hibernate.hql.ast.QuerySyntaxException when running a JPQL query with a MEMBER OF on an @ElementCollection
--------------------------------------------------------------------------------------------------------------

                 Key: HHH-5209
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5209
             Project: Hibernate Core
          Issue Type: Bug
          Components: core, entity-manager
    Affects Versions: 3.5.1
         Environment: Hibernate EM 3.5.1, HSQLDB, Derby, H2
            Reporter: Pascal Thivent
            Priority: Blocker
         Attachments: QueryTest.patch

I have an entity with an attribute of type {{Set<String>}} annotated as {{@ElementCollection}}. Running a query with a {{MEMBER OF}} on this attribute fails with Hibernate (but works with the RI):

{code} 
select user from User user where :role member of user.roles
{code} 

This is valid JPQL but Hibernate is not able to generate the corresponding SQL properly:

{code:java}

{code} 

I'm not sure this would be the right place (this seems to be a problem in Hibernate Core actually) but I've implemented a test method in {{org.hibernate.ejb.test.query.QueryTest}} demonstrating the problem. The patch is attached.
