HTTP client metrics issue for Pooled ConnectionProvider - Unable to start reactive web server

Wanted to use additional HTTP client metrics for Pooled ConnectionProvider metrics:

reactor.netty.connection.provider.total.connections  
reactor.netty.connection.provider.active.connections  
reactor.netty.connection.provider.idle.connections  
reactor.netty.connection.provider.pending.connections

When try to run below sample, it works and shows some active connections etc in console

public static void main(String[] args) {
    Metrics.globalRegistry 
           .config()
           .meterFilter(MeterFilter.maximumAllowableTags("reactor.netty.http.client", "URI", 100, MeterFilter.deny()));

    HttpClient client =
            HttpClient.create()
                      .metrics(true, s -> {
                          if (s.startsWith("/stream/")) { 
                              return "/stream/{n}";
                          }
                          else if (s.startsWith("/bytes/")) {
                              return "/bytes/{n}";
                          }
                          return s;
                      }); 

    client.get()
          .uri("https://httpbin.org/stream/2")
          .responseContent()
          .blockLast();

    client.get()
          .uri("https://httpbin.org/bytes/1024")
          .responseContent()
          .blockLast();
}

But when I try to integrate this same in my project, then it results in error. Even I tried with basis HttpClient metrics sample by integrating in my project,

@Component public class HttpClientConfig implements BeanPostProcessor {

@Override
public Object postProcessAfterInitialization(Object bean, String beanName) throws BeansException {

    HttpClient client =
            HttpClient.create()
                    .host("example.com")
                    .port(80);

    client.get()
            .uri("/")
            .response()
            .block();
    return client;
}

}

It shows below errors:--

I have tried everything found while searching for it (Although very limited found). Nothing worked for me. Stucked in it from few days. Please guide, how to use the above Pooled ConnectionProvider metrics. and why these errors are coming...
