Here is an overview of the issue:
---------------------------------------------------------------------
        Key: HB-517
    Summary: Expression.in(String, Collection) doesn't check Collection.size()==0 automatically
       Type: Bug

     Status: Unassigned
   Priority: Major

    Project: Hibernate2
   Versions:
             2.1 rc1

   Assignee: 
   Reporter: fafnirchen

    Created: Thu, 4 Dec 2003 12:56 AM
    Updated: Thu, 4 Dec 2003 12:56 AM
Environment: w2k, jdk1.4

Description:
I used Expression.in(column:String, inValue:Collection) to add query condition. As for argument Collection it is a dnynamic List. When inValue.size()==0 I do not want Expression add condition string like xxxColumn in (?).Now when inValue.size()==0 Hibernate2 throws Exception when Criteria.list().
The fragment of my code is the following.

			Criteria crit = session.createCriteria(WsStockPriceModel.class);

			crit.add(
				Expression.between(
					"pubDate",
					model.getSearchBeginDate(),
					model.getSearchEndDate()));
			crit.add(Expression.in("productName",
				model.getSearchProductNames()));
			crit.setFirstResult(firstResult);
			crit.setMaxResults(pageSize);

			List list = crit.list();

And the fragment of Exception is the following.
java.lang.NegativeArraySizeException
