Environment

Release : 11.5

Component : CA Workload Automation System Agent

Resolution

Older system agent wasn't cleaned up correctly.
When the new agent with the softlink for the jre location was deployed, it was still looking for the old local Java.

A complete clean reinstall fixed the issue.
