The JmxRemoteLifecycleListener was not updated to take account of Oracle’s fix for CVE-2016-3427. JMXRemoteLifecycleListener is only included in EWS 2.x and JWS 3.x source distributions. If you deploy a Tomcat instance built from source, using the EWS 2.x, or JWS 3.x distributions, an attacker could use this flaw to launch a remote code execution attack on your deployed instance.
