"ArithmeticException[/ by zero]" when parsing a "polygon" "geo_shape" query with one pair of coordinates

[astefan]

For a query like this one:

{
  "query": {
    "geo_shape": {
      "location": {
        "shape": {
          "type": "polygon",
          "coordinates": [[["4.901238","52.36936"]]]
        }
      }
    }
  }
}

An "ArithmeticException: / by zero" is returned enclosed in a SearchParseException:

Caused by: java.lang.ArithmeticException: / by zero

If I increase the number of coordinates for the polygon in the query to two, a more acceptable and meaningful exception is being thrown: "IllegalArgumentException[Invalid number of points in LinearRing (found 2 - must be 0 or >= 4)]". Probably, the same exception should be thrown and returned in case of just one set of coordinates.
