Cause
Tomcat native libraries (Bootstrap.jar, tomcat-juil.jar) were copied from different versions incorrectly to WorkloadAutomationAE/webserver/bin and WorkloadAutomationAE/wcc/bin/lib folders
Resolution
- Make sure to upgrade Tomcat correctly first - Upgrade Tomcat
- Then copy the correct tomcat* files from the WorkloadAutomationAE/webserver/bin to WorkloadAutomationAE/wcc/bin/lib folder.
- Restart CA-wcc-services service
