It could be cool to have a parameter to change Hibernate's default behavior to handle non annotated fields on entity class.

By default, Hibernate considers non annotated fields as persistent field (http://docs.jboss.org/hibernate/annotations/3.5/reference/en/html/entity.html#entity-mapping-property).

Could be nice to have a global Hibernate param to change this behavior and make Hibernate only considering annotated fields and ignore non annotated ones.
