> Hi!
> I have a very _funny_ behaviour where the HttpClient seems to wrongly
> interpret the body of an HTTP response as headers, the parsing of which
> eventually leads to a java.net.SocketTimeoutException.
> The underlying cause of this seems to be a a faulty server response, i.e.,
> {noformat}
> HTTP/1.1 000 status code 000{noformat}
> Thank you Apple! /s
>
> I have managed to trace the origin of the problem to the *method
> HttpRequestExecutor#canResponseHaveBody* where, as expected, 000 is not
> considered as a valid status code.
> !canResponseHaveABody.png!
> !doReceiveResponse.png!
> So what happens seems to be that the status line and headers get parsed. The
> 000 is not considered valid and that ends the processing of the response.
> Then the rest of the response (the body) seems to go through the parsing
> procedure again in *DefaultHttpResponseParser#parseHead*. The body is of
> content type application/json. Eventually the following exceptions gets
> thrown after a while:
> {code:java}

> I'm not really familiar if 000 is even a valid return code. When querying the
> server with some other HTTP tools like Postman, I do get the json response
> with a status code 000.
> Do you guys think this is something that can be fixed in HttpClient or at
> least handled by some sort of an error?
