Ignorecase for In-Criterion
===

i'd like to select items case insensitive with an In-Criterion with Hibernate Criteria API.
E.g.

    Criteria crit = session.createCriteria(Item.class);
    crit.add(Restrictions.in("prop", valueList).ignoreCase());

Unfortunately the Criterion class doesn't has an ignoreCase method.
HQL is not an alternative.
