             Summary: Flows with SolrProcessor configured to use SSLContextService is failing
                 Key: NIFI-7294
                 URL: https://issues.apache.org/jira/browse/NIFI-7294

After applying the fix in NIFI-7269, flows using SolrProcessors that are configured to use SSLContextService are failing with exception:

This is because of the new httpclient version that was pulled as a dependency as part of the solrj upgrade in NIFI-7269. The getConnectionManager method in HttpClient is deprecated and the way to set the schema registry has changed in the new version of HttpClient. The problematic code is 
{code}
httpClient.getConnectionManager().getSchemeRegistry().register(httpsScheme);
{code}
in function createSolrClient. There is no test coverage for this function which is why it was not detected in the code changes for NIFI-7269.
