MQ Traces were not visible after configuring MQMonitor agent as required.

We are getting the following error when MQ transactions are being executed:

Exception in thread "<QUEUE_NAME>|<host-name>" java.lang.NoSuchMethodError: method <init>()V not found

The exception indicates that the which is required for MQ traces on MQMonitor side, is either missing or not configured in the correct order in the classpath.
