Otpimistich Lock get All Conflicting entities

Question

try{
  ....
}catch(ObjectOptimisticLockingFailureException e){
   e.getIdentifier(); -> this is just one id of conflicting entity.
}

How to get all conflicting entities???

What about this solution ?

List<Long> ids = Lists.newArrayList();
try{

}catch(ObjectOptimisticLockingFailureException e){
  ids.add(e.getIdentifier());
}
if (!ids.isEmpty()){
  throw MyRuntimeException(ids);
}
