+ operator in JPQL subselect query results in NullPointerException
------------------------------------------------------------------

                 Key: HHH-5311
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5311
             Project: Hibernate Core
          Issue Type: Bug
    Affects Versions: 3.5.0-Final
         Environment: hibernate-3.5.0-Final.jar, java version "1.6.0_17", database platform seems irrelevant (H2 and MySQL tested)
            Reporter: Grzegorz Olędzki


When trying to use a {{+}} arithmetic operator in a subquery of my JPQL query I end up with a NullPointerException from {{org.hibernate.hql.ast.HqlSqlWalker}}.

I've played with adding/removing parentheses, aliases, but that doesn't seem to help.
