Identified as product defect.

Resolution

This issue has been resolved by L2 team and fixed under iam-updater.jar. Open a new support case and request the JAR.

Steps to apply:

- Move the existing file LISA_HOME\IdentityAccessManager\modules\com\ca\sv\iam-updater-ext\main\iam-updater.jar  to some other backup folder outside LISA_HOME

- Place the fix iam-updater.jar file in the folder LISA_HOME\IdentityAccessManager\modules\com\ca\sv\iam-updater-ext\main

- Start IAM Service.
