Mathieu Marie commented on SOLR-12848:
--------------------------------------

I am trying to use a proxy to intercept SolrJ<->Solr communications. It looks like I am hitting that issue too. 
Wondering if this one liner patch is still valid, and could be merged. This seems like a valid use case to honor the jvm flags.

> SolrJ's HttpSolrClient ignores the HTTP proxy configuration from system properties http.proxyHost and http.proxyPort. This used to work with Solr 6.6.5.
> Solr 6.6.5 used org.apache.http.impl.client.SystemDefaultHttpClient under the hood, which took system properties for HTTP proxy config into account. The deprecated SystemDefaultHttpClient class was replaced as part of SOLR-4509. SolrJ now uses org.apache.http.impl.client.HttpClientBuilder#create to create an HttpClient, but it does not call #useSystemProperties on the builder. Because of that, the proxy configuration from system properties is ignored.
