Buggy source:

Fixed version (ground truth):
@Override protected void loadContent(){

  if (extras == null) {
    AppLog.e(AppLog.T.UTILS,"String_Node_Str");
    finish();
    return;
  }
  String addressToLoad=extras.getString(URL_TO_LOAD);
  String username=extras.getString(AUTHENTICATION_USER,"String_Node_Str");
  String password=extras.getString(AUTHENTICATION_PASSWD,"String_Node_Str");
  String authURL=extras.getString(AUTHENTICATION_URL);
  if (extras.getBoolean(USE_GLOBAL_WPCOM_USER,false)) {
    username=AccountHelper.getDefaultAccount().getUserName();
  }
  if (TextUtils.isEmpty(addressToLoad) || !UrlUtils.isValidUrlAndHostNotNull(addressToLoad)) {
    AppLog.e(AppLog.T.UTILS,"String_Node_Str");
    Toast.makeText(this,getText(R.string.invalid_site_url_message),Toast.LENGTH_SHORT).show();
    finish();
  }
  if (TextUtils.isEmpty(authURL) && TextUtils.isEmpty(username) && TextUtils.isEmpty(password)) {
    String referrerUrl=extras.getString(REFERRER_URL);
    if (!TextUtils.isEmpty(referrerUrl)) {
      Map<String,String> headers=new HashMap<>();
      headers.put("String_Node_Str",referrerUrl);
      loadUrl(addressToLoad,headers);
    }
 else {
      loadUrl(addressToLoad);
    }
  }
 else {
    if (TextUtils.isEmpty(authURL) || !UrlUtils.isValidUrlAndHostNotNull(authURL)) {
