[kerkhofsd]

The extractHttpServletResponse method of the WebScriptUtil falsy returns null.

Cause:
AnnotationWebscriptResponse

	@Override
	public WebScriptResponse getNext() {
		if (response instanceof WrappingWebScriptResponse) {
			return ((WrappingWebScriptResponse) response).getNext();
		} else {
			return null;
		}
	}
