3 tables : USERS, GROUPS, USERSGROUPS(relation many to one on the first two)

When I execute a query on USERGROUPS(see below) , I recieve data from USERGROUPS, USERS and GROUPS retrun fields values "null" for "String types" and "0" for "integer type".

Work's fine before with Hib 2.1, some extra info with Hib 3.0?

Remark: leazy=false (default)
