[jira] [Commented] (SOLR-6239) HttpSolrServer: connection still allocated

    [ https://issues.apache.org/jira/browse/SOLR-6239?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14058724#comment-14058724 ] 

Sergio Fernández commented on SOLR-6239:
----------------------------------------

The recommended way, by Httpcomponents 4.1, is to close connection and release any underlying resources:

{code}EntityUtils.consume(HttpEntity){code}

But not sure how it fits with the current code...
