If you try to check the updates and you have a connectivity problem or the drupal server is down you receive a large warning list without any explication.

Maybe should be easy to show a simple message like: "Impossible to connect to the update server" than this warnings list:

Failed to get available update data for one project.

The try catch structure is not working fine

  try {
    $xml = new SimpleXMLElement($raw_xml);
  }
  catch (Exception $e) {
    // SimpleXMLElement::__construct produces an E_WARNING error message for
    // each error found in the XML data and throws an exception if errors
    // were detected. Catch any exception and return failure (NULL).
    return;
  }

This solve the problem in my case

  try {
    $xml = @new SimpleXMLElement($raw_xml);
  }
  catch (Exception $e) {
    // SimpleXMLElement::__construct produces an E_WARNING error message for
    // each error found in the XML data and throws an exception if errors
    // were detected. Catch any exception and return failure (NULL).
    return;
  }
