@techmoksha I tried hard, but I can not reproduce the exception using Play-Scala 2.6.13.
Can you provide us a reproducer that "works" (throws the exception)?

I used following test, because the example you give in the original discussion does compile...

package controllers

import org.scalatestplus.play._
import org.scalatestplus.play.guice._
import play.api.test.Helpers._
import play.api.test._

class HomeControllerSpec extends PlaySpec with GuiceOneAppPerTest with Injecting {

  "HomeController POST" should {

    "not throw an exception with empty body" in {
      val request = FakeRequest(POST, "/uri").withHeaders("<myheader>" -> "headervalue")
      val result = Helpers.route(fakeApplication, request)
    }
  }
}

I had a look again because I was working on related code. However, I am still not able to reproduce this. The only place where jRoute is called is inside Java's route helper. And because this Java router helper method expects a RequestBuilder, we can be sure that this RequestBuilder always has a RequestBody set (just look how RequestBody is implemented, you will not be able to set null as body) (This RequestBody can in turn contain null but that does not matter here). So it's not possible to run into the NPE (also I was not able to do so).
So maybe the author did use jRoute directly and passed null explictly as body... However this is not how this should be used.

Because there is no reproducer I will close this.
Feel free to re-open if you know how to reproduce this.
