Kirill Kadyrko commented on CXF-4482:
-------------------------------------
Hi,
I think we should definitely use CRLFCRLF to separate HTTP headers and a body.
What took place before the fix, was actually THREE line breaks after HTTP
headers (CRLFCRLFCRLF). Maybe the most reasonable fix is to just remove the
last CRLF? I've attached a screenshot.

> _AttachmentSerializer_ always puts an extra new line before writing the root
> attachment boundary and headers. Because of that the HTTP request which
> contains only attachments has two line breaks after request headers. That is
> not understood by some service providers and they do not process the request.
> For example:
> {code}
> ...
> Pragma: no-cache
> Connection: keep-alive
> Content-Length: 92010
> <new line>
> <another new line>
> --uuid:467a6f94-55c4-43fe-9e4a-09d63b0bc589
> Content-Type: application/xml
> ...
> {code}
