特殊的索引格式 druid parser 会失败

CREATE TABLE "item_extra" ( "id" int(10) unsigned NOT NULL AUTO_INCREMENT, "item_id" int(10) unsigned NOT NULL DEFAULT '0' COMMENT '商品id', "type" tinyint(4) unsigned NOT NULL DEFAULT '0' COMMENT '扩展属性类型，0：虚拟商品', "attr_key" varchar(50) NOT NULL COMMENT '扩展属性key', "attr_value" varchar(500) NOT NULL COMMENT '扩展属性value', PRIMARY KEY ("id"), KEY "idx_item_type_kv" ("item_id","type","attr_key","attr_value"(191)) )

使用 1.0.21 parser 会发生如下错误？
