    Description

      Whenever Thread A spends more than 10 seconds on a Connection (by retrieving records in a batch), Thread B will close connection.
      Related exceptions happen when we use "threads=" attribute for entity; usually exception stack contains message "connection already closed"
      It shouldn't happen with some JNDI data source, where Connection.close() simply returns Connection to a pool of available connections, but we might get different errors.
