Caused by: java.lang.ClassNotFoundException: org.apache.log4j.Level
-----------------
Environment
Release : 21.2.x
Cause
In this case, the /opt/IMDataAggregator/broker/apache-activemq-5.15.8/lib/optional/log4j-1.2.17.jar file was wrongly deleted by customer when trying to mitigate/solve the log4j vulnerability.
Resolution
Problem is solved by restoring that file and restarting the ActiveMQ service
