Enum literals of inner Enum classes require the use of $ in EJB-QL
------------------------------------------------------------------

                 Key: EJB-388
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/EJB-388
             Project: Hibernate Entity Manager
          Issue Type: Bug
          Components: EntityManager
    Affects Versions: 3.4.0.GA
            Reporter: Onno Molenkamp
            Priority: Minor


When I use an enum literal of an inner enum class in an EJB-QL query using the normal Java syntax for enum literals, I get the following exception:

Caused by: org.hibernate.hql.ast.QuerySyntaxException: Invalid path: 'some.package.SomeClass.SomeEnum.ENUMVALUE' [select x from some.package.SomeClass x where x.enumproperty = some.package.SomeClass.SomeEnum.ENUMVALUE]

        ... 85 more

A workaround is to use the syntax some.package.SomeClass$SomeEnum.ENUMVALUE, but I think the syntax I tried to use should also work.
