  <p>In the project at some location, queries are working properly where I am able to log in and execute some operations. For some queries, it is not working.</p>
  
  <p>Does not seem to entity or query related issue. Some search around the net mentions this to be a bug in Entity manager when not closed "em.close()" 
  Not sure on this as already it has been working for other queries.</p>
  
  <p>Please help</p>
  
  <p>Thanks
  Regards</p>
