Running the sample server code on Netbeans v8.1 with SoapUI v5.3.0 as the client POSTing to http://localhost:8080/, I captured the following response:
HTTP/1.1 200 OK
Date: Mon, 05 Jun 2017 13:53:45 GMT
Server: Test/1.1
Content-Length: 1346189

Please note the missing Content-Type HTTP header.
The Content-Type header is also missing from the response in my own curl
v7.53.0 tests.
The additional testing and verification is appreciated.

I see no evidence supporting this assertion.
