> The hint, 'openjpa.hint.UseLiteralInSQL', is not properly converting a boolean to an int.  To illustrate this, lets take this entity:
> public class MyEntity implements Serializable {
>  @Id
>  private Integer pk;
>  private boolean flag;
> ..........
> With this entity, lets take this test:
> Query q = em.createQuery("SELECT f FROM MyEntity f WHERE f.flag = true");
> q.setHint("openjpa.hint.UseLiteralInSQL", "false");  //false is the default
> q.getResultList();
> With this code, the following SQL will be generated:
> SELECT t0.pk, t0.code, t0.code2, t0.flag FROM MyEntity t0 WHERE (t0.flag = ?)  [params=(int) 1]
> Next, lets take this code:
> Query q = em.createQuery("SELECT f FROM MyEntity f WHERE f.flag = true");
> q.setHint("openjpa.hint.UseLiteralInSQL", "true");
> q.getResultList();
> With this code, the following SQL will be generated:
> SELECT t0.pk, t0.code, t0.code2, t0.flag FROM MyEntity t0 WHERE (t0.flag = true)
> However, in the latter case where UseLiteralInSQL=true, the following SQL should be generated:
> SELECT t0.pk, t0.code, t0.code2, t0.flag FROM MyEntity t0 WHERE (t0.flag = '1')
> Thanks,
