E então...
Alguem sabe outra maneira de resolver esse problema ?
Exception Message: a different object with the same identifier value was already associated with the session: [Usuario#5]
pq com o usuarioInstance = usuarioInstance.merge()
eu pego outro erro
Exception Message: Row was updated or deleted by another transaction (or unsaved-value mapping was incorrect): [Usuario#5]
