json类型字段bug

有个bug在1.0.23下

com.alibaba.otter.canal.parse.exception.CanalParseException: parse row data failed. Caused by: com.alibaba.otter.canal.parse.exception.CanalParseException: parse row data failed. Caused by: java.lang.IllegalArgumentException: illegal json data at com.taobao.tddl.dbsync.binlog.JsonConversion.parse_scalar(JsonConversion.java:150) at com.taobao.tddl.dbsync.binlog.JsonConversion.parse_value(JsonConversion.java:67)

数据库版本 mysql-5.7.11-winx64 数据库结构

CREATE TABLE customer_data ( id bigint(19) unsigned NOT NULL AUTO_INCREMENT, supplier_id bigint(19) unsigned NOT NULL COMMENT '商户id', customer_id bigint(19) unsigned NOT NULL, customer_data json DEFAULT NULL COMMENT '顾客标准属性', customer_ext_data json DEFAULT NULL COMMENT '顾客扩展属性', PRIMARY KEY (id), UNIQUE KEY uk_cust (customer_id) ) ENGINE=InnoDB AUTO_INCREMENT=26036 DEFAULT CHARSET=utf8mb4;

debug后就是149行str_len==0
