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

CustomHttpRequest is not a standard JAX-RS context object. Let's say it accidentally implements HttpServletRequest interface.

If I am asking for @Context CustomHttpRequest context object but cxf would like to give me the equivalent of @Context HttpServletRequest and it fails with ClassCastException. This is a bug for me.

> I tried to wrap HttpServletRequest by using ContextProvider, lets assume such a simple implementation:
> @Provider
> public class CustomHttpRequestContextResolver implements ContextResolver<CustomHttpRequest> {
> 	@Context
> 	private HttpServletRequest request;
>    public CustomHttpRequest getContext(Class<?> type) {
>      return new CustomHttpRequest(request); 
>    }
> }
> However, before calling context provider CXF first calls JAXRSUtils.createServletResourceValue() method that tries to cast HttpServletRequest into my wrapped request and it fails with ClassCastException.
> I havent found in JAX_RS spec anything telling that such a ContextResolver is forbidden.This works also with Apache Wink.
