We also faced same issue when we were running embedded solr 6.1 server. Actually I faced the same in our integration environment after deploying project. Solr 6.1 is using http client 4.4.1 which I think embedded solr server is looking for. I think when solr core is getting loaded then old http client is getting loaded from some where in your maven. Check dependency tree of your pom.xml and see if you can exclude this jar getting loaded from anywhere else. Just exclude them in your pom.xml. I hope this solves your issue,
