 <div class="block">"eclipselink.result-set-access"
  <p>Configures if this read object(s) query should keep result set until all result object(s) are built.
  That allows to avoid getting potentially huge objects (LOBs) from ResultSet in case they would not be used
  because the object is found in the cache.
  Valid values are:  HintValues.PERSISTENCE_UNIT_DEFAULT, HintValues.TRUE, HintValues.FALSE,
  "" could be used instead of default value HintValues.PERSISTENCE_UNIT_DEFAULT</div>
