Elastic Agent Tomcat Integration Error

What versions of Tomcat are supported by the Elastic Agent Tomcat integration? I have an instance which runs an older version of Tomcat (8.5), and I get dissect_parsing_error in my events, which are pushed to Elasticsearch, even though the log format appears to be identical, as far as I can tell.

When I set the Agent log level to debug and set the integration to collect debugging info, I see the following in the agent logs:
