Hi,
I write a outward interceptor and put it after JAXRSOutInterceptor to
clean up some resouces. When cleaning up the resources, there might be some
exceptions happening. Then I directly set the HttpServletResponse's headers
and content to send back an appropriate response. This works even there is
a IllegalStateException thrown when later cxf's jaxrs implementation try
flush http headers to the HttpServletResponse like below. Any more
appropriate way to achieve my goal without this exception?
