es.mapping.id populates wrong value

[n0rb3rt]

Using Spark 1.5.1 and elasticsearch-spark 2.1.1 I'm setting the es.mapping.id to a field in my JSON called "feature_id". IDs are getting populated, but they don't match the value of the "feature_id" field in the document.

EsSpark.saveJsonToEs(
  rdd.map(_.toJson),
  "myindex/features",
  Map(
    "es.nodes" -> "myhost.com",
    "es.mapping.id" -> "feature_id"
  )
)

{
  "_index": "myindex",
  "_type": "features",
  "_id": "144136021837088505",
  "_score": 1,
  "_source": {
    "feature_id": 144136021837088500,
    ...
  }
}

Can you please post a sample doc? Is there another feature_id inside the document? Does it contain by any chance another 144136021837088500 - or is this number somewhere in an another document?
It looks like a bug but I'm trying to narrow down where do these numbers are coming from and thus what causes the bug to occur.

Actually I think this is a false alarm. I think the problem is my (Javascript) client incorrectly munging the Long value of feature_id. When I do it with curl everything looks good.
