                            if (logger.isTraceEnabled()) {
                                logger.trace(msg);
                            } else if (logger.isDebugEnabled()) {

                                logger.warn(msg);
                            } else if (logger.isErrorEnabled()) {

                    logger.debug("{} is not an object.", path);
                }
                break;
            default:
                logger.warn(path + " is not an object.", e);
                break;
