Description
Request.Content.getContentType()'s Javadoc reads:

[...] or null if the {@code Content-Type} header must not be set

but then HttpConnection.normalizeRequest contains this code:

            if (!headers.contains(HttpHeader.CONTENT_TYPE))
            {
                String contentType = content.getContentType();
                if (contentType == null)
                    contentType = getHttpClient().getDefaultRequestContentType();
                if (contentType != null)
                    request.addHeader(new HttpField(HttpHeader.CONTENT_TYPE, contentType));
            }

Meaning, if content.getContentType() returns null, then getHttpClient().getDefaultRequestContentType() is used. Only if the latter is also null is the content-type left unset.

Please ensure that the documentation and implementation match in this case.
