Problem:
Hibernate is executing an Update statement after a commit is called on a criteria.list()

Any ideas why this happens?

I call a commit since the code inside the try can change to a saveOrUpdate() or delete().

Hibernate version:
Hibernate 3

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

......

session = HibernateUtils.currentSession();
HibernateUtils.beginTransaction();
if (criteria_collection != null) {
Criteria criteria = session.createCriteria(entityClass);

for (Criterion crit: criteria_collection) {
criteria.add(crit);
}

result = criteria.list();
} else {
result =
session.createQuery(" from " + entityClass.getName()).list();
}

.......

HibernateUtils.commitTransaction();
} catch (Throwable t) {
log.error("Unexpected error!", t);
HibernateUtils.rollbackTransaction();
} finally {
HibernateUtils.closeSession();
}

Name and version of the database you are using:
Oracle 10g

The generated SQL (show_sql=true):
