Recover from Hibernate Optimistic Locking exception

Question

I have been facing a strange problem lately. I tried to handle the the stale state exception gracefully . But in catch block it still throws the exception . Following is the code snippet

public void saveObject(Object ob){
   try{
      sessionFactory.getCurrentSession().saveOrUpdate(ob);
   }catch(org.springframework.orm.hibernate5.HibernateOptimisticLockingFailureException e){
       object latestObject = // get latest object from db;
       copyFieldsFromObToLatestObject(ob,latestObject);
       // print the version of of both object

    LOGGER.info(" ui_version="+ob.getVersion().longValue()+" 
                 entity_version="+latestObject.getVersion().longValue());
          // the ui _version is less than entity_ version as expected 

        sessionFactory.getCurrentSession().saveOrUpdate(latestObject); // at this line I still get the same optimistic locking exception 

   }
}
 /**

 ob2 is the latest object which contains the correct  version hence copying the fields from previous object to this latest object
**/
private void copyFieldsFromObToLatestObject(ob1,ob2){
    ob2.setA(ob1.getA())..
   so on
}

Can some one take a look at this . I am unable to get the reason why it still throws optimistic locking exception after handling it correctly

EDIT 1 : the stacktrace :

Can you please post the exceptions and the stacktraces you get — Simon Martinelli, Apr 29 '20 at 09:30

In the catch block you should catch the exception that is thrown and that you want to process. You catch Optimistic locking exception. I cannot even imagine how this compiles. Try to replace it with name of the exception in stack trace?

Problem was solved , I was copying the version of associated child entities in the to field as well which lead to older version of child entities being getting saved and hence leading to error
