--------------------------------

             Summary: jax-rs2 request filter is unable to modify request header by adding a new header 
                 Key: CXF-4986
                 URL: https://issues.apache.org/jira/browse/CXF-4986
             Project: CXF
          Issue Type: Bug
          Components: JAX-RS
    Affects Versions: 2.7.2
         Environment: cxf on tomcat
            Reporter: abdelgadiri


I have a filter implementation as follows

@Provider
public class AuthSessionFilter implements ContainerRequestFilter {
    public AuthSessionFilter() {
    }

    @Override
    public void filter(ContainerRequestContext requestContext) throws IOException {      

        Object sessionId = requestContext.getProperty("sessionId");
        if (sessionId == null || GeneralUtils.isNullOrBlank(sessionId + "")) {
            requestContext.abortWith(Response.status(Response.Status.UNAUTHORIZED)
                    .entity("missing sessionId").build());
        }

        requestContext.getHeaders().putSingle("sessionId", sessionId+"");
    }
}


The line requestContext.getHeaders().putSingle("sessionId", sessionId+""); is not making the added sessionId header available when trying to obtain it from my resource. getHeaders() is supposed to return a mutable map in accordance with the spec, but its implementation 'ContainerRequestContextImpl' is returning a readonly map instead. it returning:

  return new MetadataMap<String, String>(
            (Map<String, List<String>>)m.get(Message.PROTOCOL_HEADERS), false, true, true);

where it is passing 'true' for the readonly parameter.
