Description

I have set up a CXF server endpoint (v. 3.1.8) using JAX-WS with JAXB databinding and MTOM. Everything else works correctly but the custom HTTP headers that I add with an outbound interceptor to the response messages seem to disappear. The custom headers are in place for other than MTOM-enabled endpoint responses. I have followed the guidance (1) in my interceptor which adds the headers ("prior to WRITE phase").

I suspect the problem is in AttachmentOutInterceptor (2) as it does not respect the headers possibly specified by other interceptors ("root headers" are always empty)? I guess the "root headers" should be initialized from the current message state.

I also tried (against the mentioned guidance) adding my interceptor after AttachmentOutInterceptor (and also after AttachmentOutInterceptor#AttachmentOutEndingInterceptor) but it did not help.
