> Test org.hibernate.ejb.test.QueryTest#testIsNull fails due to this query:
> select i from Item i where (i.descr is null and :descr is null) or i.descr = :descr
> When changing the query to what it reads below, it works properly:
> select i from Item i where i.descr = :descr or (i.descr is null and :descr is null)
> As this happened only with PostgreSQL, I assume this is an issue with either the driver or with the database itself. Will dig into pgsql's site to find out more about this issue.
