Hi,
On trunk version, JPQL query accepts empty list for IN parameter.
Following pass:
public void testEmptyInExpression() {
String jpql = "select o from Book o where o.ISBN in (:ids)";
List<String> ids = new ArrayList<String>();
assertTrue(_em.createQuery(jpql).setParameter("ids",
ids).getResultList().isEmpty());
}
For further investigation, please post
1. The query string
2. Exact way of setting the IN parameter values
3. Error stack
