Fixed version (ground truth):

    throw new ServiceException(ErrorDataFactory.createErrorData(ErrorConstants.SVC_SECURITY_CLIENTTOKENRETRIEVAL_HANDLER_INIT_FAILED,ErrorConstants.ERRORDOMAIN.toString(),new Object[]{"String_Node_Str"}));
  }
  if (!("String_Node_Str".equalsIgnoreCase(m_tokenRetrievalStyle)) && !("String_Node_Str".equalsIgnoreCase(m_tokenRetrievalStyle))) {
    logCalMsg("String_Node_Str");
