> In a joined-subclass structure when trying to use query.iterate(), to use cache and lazy, hibernate translate the query "from Activation activation where activation.class = Activation" to an mal-formed SQL query. The SQL query string that it creates is "select activation0_.id as col_0_0_ from activation activation0_ where case when activation0_1_.fk_id_activation is not null then 1 when activation0_.id is not null then 0 end=0".
