Collection mapping in revers enginering

Hi,
Im i have oracle database 10g, and му goal is to build sources of java POJO classes via hbm2java. I'm trying to do it via revers enginering from database - to POJO. The pojo classes, has been correctly built , but by default the ralationship manytomany and onetomany are maped as: java.util.Set<?> for example:

private Set<Document> documentsForMotherId = new HashSet<Document>(0);

,but i need it to be mapped as java.util.Collection<?>:
@ManyToMany(mappedBy = "personCollection1")
private Collection<Document> documentCollection1;

and without initial initialisation
Is there possibility to adjast hibernate.reveng.xml to make such generation of POJO sources ?

Map the property with the following meta-attributes:
<meta attribute="property-type">java.util.Collection</meta>
<meta attribute="default-value">null</meta>

why do you need no init and just Collection ? Hibernate will use a hashset anyway ?
