I have 2 classes mapped using implicit table per concrete class hierarchy.
Criteria Queries on Super class throw a ClassCastException(see below).
Non criteria queries work. Queries on the subclass work. Other mapping strategies also work.

Hibernate version: 3.2

Mapping documents:

<hibernate-mapping package="com.gigaspaces.test.cacheloader.objects">
<class
name="Super">

<id name="id" type="string">
<column name="ID" length="200"/>
<generator class="assigned" />
</id>

</class>

<class
name="SubClass">

<id name="id" type="string">
<column name="ID" length="200"/>
<generator class="assigned" />
</id>

<property name="username" type="string">
<column name="USERNAME" length="20" />
</property>

<property name="firstname" type="string">
<column name="FIRSTNAME" length="20" />
</property>

<property name="lastname" type="string">
<column name="LASTNAME" length="20" />
</property>

</class>

Code between sessionFactory.openSession() and session.close():

Transaction tx = session.beginTransaction();
Example example = Example.create(template);
Criteria query = session.createCriteria(template.getClass())
.add(example);

query.setCacheMode(CacheMode.IGNORE);
query.setCacheable(false);
query.list();
