Issue/Introduction

While upgrading the CA Identity Manager the upgrade process appears to complete successfully but when JBoss\ Wildfly is started errors are encountered.

Environment

All Identity Manager

Cause

This issue is caused by the fact that some older jar files were not removed from the IAM folders during upgrade. The inclusion of these erroneous files stopped the App servers starting.

Resolution

Removing old .jar files left behind in the <%JBoss_Home%>/standalone/deployments/iam_im.ear allows the App server to start correctly.
