             Summary: NullPointerException in ImplicitHttpServletObjectsProducer.getCookies if not Cookies
                 Key: SOLDER-334
                 URL: https://issues.jboss.org/browse/SOLDER-334
             Project: Solder
          Issue Type: Bug
    Affects Versions: 3.1.0.Final
            Reporter: Thomas Frühbeck


If no Cookies in Request, request.getCookies() returns null.

>   @Produces
>   @RequestScoped
>   protected List<Cookie> getCookies() {
>       return Arrays.asList(getHttpServletRequest().getCookies());
>   }

When using the Producer, there is no possibility to identify, if cookies are set or not, the proxy will not be null:

So by simply invoking :

	@Inject
	private List<Cookie> cookies;
	
	public void handleInit(@Observes HttpServletRequest request) {
		log.info("handling Request: "+request.getRequestURI());
		if (cookies != null) {
				for (Cookie cookie : cookies) { 
					System.out.println("Found Cookie: "+cookie);
				}
        ...

I get:

description The server encountered an internal error () that prevented it from fulfilling this request.
