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.
