Module groovy-all 2.4.7 error accessing agents post upgrade

Products

• CA Automic Applications Manager (AM)

Issue/Introduction

Post upgrade to 9.3.4, I get the below error when trying to access any of the agents:

Error message:
Conflicting module versions. Module groovy-all is loaded in version 2.4.16 and you are trying to load version 2.4.7

Error message:
Could not initialize class org.codehaus.groovy.runtime.InvokerHelper

Once I get past the errors, all of the agents login dropdowns are empty, none of my logins appear. All of my jobs run fine, all of the schedules are working. I just cant do anything with the agents other than stop/start them.

Environment

Release : 9.3.4

Component : APPLICATIONS MANAGER

Resolution

The error usually occurs due to unwanted / missing jar files in the Applications manager Client Home\Jars folder.

In this case,  removing the groovy-all-2.4.7.jar in the AM_CLIENT/jars folder resolved the issue.
