Is this a bug in the feign rule for the latest feign-core?

[qbwu]

In rule/feign/src/main/java/io/opentracing/contrib/specialagent/rule/feign/FeignAgentIntercept.java：

 private static Request inject(final Tracer tracer, final SpanContext spanContext, final Request request) {
    final HashMap<String,Collection<String>> headersWithTracingContext = new HashMap<>(request.headers());
    tracer.inject(spanContext, Format.Builtin.HTTP_HEADERS, new HttpHeadersInjectAdapter(headersWithTracingContext));
    return Request.create(request.method(), request.url(), headersWithTracingContext, request.body(), request.charset());
 }

The ending return statement calls the Request.create, which is a deprecated method for the latest feign-core, and it will create a Request with requestTemplate = null, and when others try to use the RequestTemplate to revise the Request later, it will throw a NPE.
