Setting Content Type Header with Play Framework Java

I'm using Play Framework 2.2.1 with Java. I'm trying to test my Controllers, in doing so I need to set the Content-Type header to "application/json". I've tried this using 'withHeader("Content-Type", "application/json") as well as 'withJsonBody' on my FakeRequest. Whenever I use either of these methods, it seems I get a null pointer exception. Any ideas on if this is a problem with how I'm setting the header?

FakeRequest fr = new FakeRequest("PUT", "/create");
fr.withHeader(CONTENT_TYPE, "application/json");

//I have tried this in place of calling withHeader as above
//JsonNode arg0 = Json.parse("{\"test\":1}");
//fr.withJsonBody(arg0);


 try {
     Result result = Helpers.route(fr);
     assertThat(result).isNotNull();
     assertThat(status(result)).isEqualTo(CREATED);
 }catch(Throwable t) {
     t.printStackTrace();
 }

This is the stack trace I get:

I do it this way

response().setHeader(CACHE_CONTROL, "max-age=3600");
response().setContentType("text/html; charset=iso-8859-1");
