PropertyAccessException using spring and hibernate, any clues?

[Marcos Maia]

org.springframework.orm.hibernate3.HibernateSystemException: exception setting property value with CGLIB 
(set hibernate.cglib.use_reflection_optimizer=false for more info) setter of br.com.dataminder.model.Ator.setFilmes; 
nested exception is org.hibernate.PropertyAccessException: exception setting property value with CGLIB 
(set hibernate.cglib.use_reflection_optimizer=false for more info) setter of br.com.dataminder.model.Ator.setFilmes

My relationship is mapped like this:

    
/**
* @hibernate.set table="filme_ator" cascade="save-update" lazy="false"
* @hibernate.collection-key column="ator_id" inverse="true"
* @hibernate.collection-many-to-many class="br.com.dataminder.model.Filme" column="id"
* @hibernate.
* hibernate.cglib.use_reflection_optimizer=false
*/
 
public List getFilmes()
{ return filmes; }
 
/**
* @hibernate.set table="filme_ator" lazy="false"
* @hibernate.collection-key column="filme_id"
* @hibernate.collection-many-to-many class="br.com.dataminder.model.Ator" column="id"
 */
public List getAtores()
{ return atores; }
