> _public PoolingHttpClientManager(int maxTotal, int maxPerRoute,
> SSLConnectionSocketFactory sslConnFactory)_
> _{ this.maxTotal = maxTotal; this.maxPerRoute = maxPerRoute;
> Registry<ConnectionSocketFactory> registry = null; registry =

> *I used the upper configuration to get the connection pool, and got the

> _HttpClients.custom()_
> _.setConnectionManager(this.gcm)_
> _.setConnectionManagerShared(true)_
> _.setKeepAliveStrategy(getKeepAliveStrategy())_
> _.setDefaultRequestConfig(requestConfig);_
> Then I got the following error:
