JPA Version column isn't updating after merge() -

-

i'm updating entity via entitymanager#merge() new jpa version number jpa isn't being reflected correctly in returned entity.

@stateless @transactionattribute(transactionattributetype.required) public class leadservice {     @persistencecontext(name = "joose")     private entitymanager em;      public lead createorupdatelead(lead lead) {         if (lead.getid() != null) {             em.merge(lead);         } else {             em.persist(lead);         }         return lead;     }

how should deal this? thanks!
