+ 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 Attachments: HHHPlusSignProject.zip 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.
