Hi,
SolrJ 6.6.5 used org.apache.http.impl.client.SystemDefaultHttpClient
under the hood, which took system properties for HTTP proxy config into
account (http.proxyHost and http.proxyPort).
The deprecated SystemDefaultHttpClient class was replaced as part of
SOLR-4509. And with Solr 7.5.0 I'm now unable to use an HTTP proxy with
SolrJ at all (not using Solr Cloud here). SolrJ 7.5 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.
Is there some other way to configure an HTTP proxy, e.g. with
HttpSolrClient.Builder? I don't want to create an Apache HttpClient
instance myself but the builder from Solrj (HttpSolrClient.Builder).
Thanks in advance,
Andreas
