Steps to Reproduce
Clarifying Information
The JMXLifecycle feature is enabled in one of the following ways:
  • Through the tcman / pasman command. For example: <pas instance>\bin\tcman.bat feature JMXLifecycle=on
  • By manually uncommenting the relevant section in the <pas instance>\conf\server.xml file. For example:
  <Listener className="org.apache.catalina.mbeans.JmxRemoteLifecycleListener"
            rmiRegistryPortPlatform="${psc.as.jmxregistry.port}" 
            rmiServerPortPlatform="${psc.as.jmxserver.port}" />
  • Within OpenEdge Management (OEM) / OpenEdge Explorer (OEE) through the JMX page of the PASOE instance. For example:

Error Messagejava.lang.ClassNotFoundException: org.apache.catalina.mbeans.JmxRemoteLifecycleListener

[main] org.apache.catalina.startup.Catalina.parseServerXml - Unable to load server configuration from [<PASOE Instance Path>\conf\server.xml]
org.xml.sax.SAXParseException: Error at line [69] column [64]: [org.apache.catalina.mbeans.JmxRemoteLifecycleListener]
Defect NumberOCTA-44310, OCTA-52221, OCTA-66784
Enhancement Number
Cause
The JmxRemoteLifecycleListener class has been removed in Tomcat 8.5.75 and Tomcat 9.0.57 as the features it provides are now available in the remote JMX capability included with Java.

The Tomcat version used by PASOE has been upgraded in OpenEdge 11.7.20, 12.2.8, 12.6 and later releases. So the latest OpenEdge releases do not support the JmxRemoteLifecycleListener class anymore.
Resolution
Disable the JMXLifecycle feature and follow the steps from the following KB article to enable JMX:
