code: public Map<String,String> getDefaultValidatorInfo() {
  
          if (defaultApplication != null) {

docs: <p class="changed_added_2_0">Return an immutable <code>Map</code> over
  the set of currently registered default validator IDs and their class
  name for this <code>Application</code>.</p>
  
  <p>An implementation is provided that returns <code>Collections.emptyMap</code>
  so that users that decorate
  the <code>Application</code> continue to work.
