Don't break the loop

It is important, that the "Error constructing documents to index..." are logged to the watchdog. But why is there a break; to exit the loop?

  foreach ($rows as $row) {
    try {
      $callback($documents, $row->nid, $namespace);
      // Variables to track the last item changed.
      $position['last_change'] = $row->changed;
      $position['last_nid'] = $row->nid;
    }
    catch (Exception $e) {
      // Something bad happened - don't continue.
      watchdog('Apache Solr', ' Error constructing documents to index <br /> !message', array('!message' => nl2br(strip_tags($e->getMessage()))), WATCHDOG_ERROR);
      break;
    }
  }

We use Tika to attach PDF-content to the node and sometimes PDF's are corrupt or protected and an exception occurs. Then all other documents in $rows would not be indexed.

Is there a reason, why this break in the loop is necessary?

Thanks,
