   We have a supported list, and 2.x is clearly too old for a community to support. No way is willing to do that. You could write your own plugin, it is not hard. And remove existing ES 6/7 plugins from your agent/plugins. You should be good.

   This log is very clear, that, you are facing some plugins incompatible with ElasticSearch 5. Nothing related to the Tomcat.
