Adding "slf4j-simple-1.7.25.jar" to the zip readonlyrest-plugin and reinstall solve the problem. http://www.slf4j.org/download.html

it's been fixed c08cd639c9c651fd6b72b14e786a8c6e685b4eb9 and revert 0179bbdf6b6a2b17d5130d48c2507e7bd1e24cb3 for some reason. for me it's works just fine with the slf4j-simple. Readonlyrest 1.16.13 Elasticsearch 5.6.4 Ubuntu 16.04.3
