    [ https://issues.apache.org/jira/browse/CXF-6356?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14501048#comment-14501048 ] 

iris ding commented on CXF-6356:
--------------------------------

After debugging, I found out we missed to support Date Header in org.apache.cxf.jaxrs.impl.RuntimeDelegateImpl:
  public RuntimeDelegateImpl() {
        headerProviders.put(MediaType.class, new MediaTypeHeaderProvider());
        headerProviders.put(CacheControl.class, new CacheControlHeaderProvider());
        headerProviders.put(EntityTag.class, new EntityTagHeaderProvider());
        headerProviders.put(Cookie.class, new CookieHeaderProvider());
        headerProviders.put(NewCookie.class, new NewCookieHeaderProvider());
        headerProviders.put(Link.class, new LinkHeaderProvider());
        //Proposed fix start
        headerProviders.put(Date.class, new DateHeaderProvider());
        //Proposed fix  end
    }

I have attached the added DateHeaderProvider.java in this defect as well. 

After this, my test scenario can run smoothly.

Thanks & Best Regards,
