Error on alfresco start : Caused by: java.lang.NoSuchMethodError: org.apache.http.conn.ssl.SSLConnectionSocketFactory.<init>(Ljavax/net/ssl/SSLContext;Ljavax/net/ssl/HostnameVerifier;)
Check and compare httpclient and httpcore jars with other installations by running command (find . | grep httpclient and find . | grep httpcore)
Remove unnecessary old version of jars. 4.5.2 version is preferable for httpclient jar and 4.4.5 for httpcore jar. old version of jars are clashing with new version of jars.
Therefore, httpcore and httpclient jars should be with one version only.
