Minor Description
Running solr with the embedded zookeeper, e.g. when running solr -e cloud results in a ClassNotFoundException / NoClassDefFoundError in the log as below. The server still functions correctly (except JettyAdminServer won't work obviously), but it looks like a problem, and isn't good for a first time user to see
