             Summary: SolrClient leaks a connection forever when an unexpected/malformed Entity is received
                 Key: SOLR-14457
                 URL: https://issues.apache.org/jira/browse/SOLR-14457
             Project: Solr
          Issue Type: Bug
      Security Level: Public (Default Security Level. Issues are Public)
          Components: SolrJ
    Affects Versions: 7.7.2
         Environment: Solr version: 7.7.2

Solr cloud enabled

Cluster topology: 6 nodes, 1 single collection, 10 shards and 3 replicas. 1 HTTP LB using

Round Robin over all nodes

All cluster nodes have gzip enabled for all paths, all HTTP verbs and all MIME types.

Solr client: HttpSolrClient targeting the HTTP LB
            Reporter: Samuel García Martínez


When the SolrJ receives a malformed response Entity, for example like the one described in SOLR-14456, the client leaks the connection forever as it's never released back to the pool.

If Solr (for whatever reason) or any intermediate networking piece (firewall, proxy, load balancer) messes up the response, SolrJ tries to release the connection but GzipDecompressingEntity#getContent fails with an IOException("Not in GZIP format"), making it impossible to release the connection.
