elastic search 5.4.版本，java api 调用出现：can not write type [class java.math.BigDecimal]

{
  "from" : 0,
  "size" : 20,
  "timeout" : "999ms",
  "query" : {
    "bool" : {
      "must" : [
        {
          "match_all" : {
            "boost" : 1.0
          }
        }
      ],
      "filter" : [
        {
          "term" : {
            "air_displacement" : {
              "value" : "1.6",
              "boost" : 1.0
            }
          }
        }
      ],
      "disable_coord" : false,
      "adjust_pure_negative" : true,
      "boost" : 1.0
    }
  },
  "_source" : {
    "includes" : [
      "product_id"
    ],
    "excludes" : [ ]
  },
  "sort" : [
    {
      "allow_sale" : {
        "order" : "desc"
      }
    }
  ],
  "track_scores" : true
}
这个请求在kibana 直接查询没有问题，但是调用java api 后 api报错，mapping设置该字段为float，

es2.2 java api就没有这个问题。目前发现只有es 5.4这个版本有问题。哪位大神之前遇到过这个问题。有什么办法可以解决
