JSON producer adds newline character to the end of JSON body

[mandrean]

I've spent the last couple of hours debugging an issue we've run into where the hash of the request body sent (using go-swagger/go-openapi) isn't what it's supposed to be (using other common tools).

I've narrowed it down to the JSON producer, which adds a newline char at the end...

So I go and have a look at the unit tests. And they seem cheat by appending a newline char in the assert:

https://github.com/go-openapi/runtime/blob/master/json_test.go#L61

assert.Equal(t, consProdJSON+"\n", rw.Body.String())

What the...?

Up on further investigation, the issue lies even further upstream with how the encoding package handles JSON streams. See https://git.io/vXr1P and https://golang.org/src/encoding/json/stream.go?s=4272:4319#L173

So I guess this issue can be closed but might be a good reference for others later on searching for the same answer.
