Deploying activiti-app and activit-admin war on Tomcat 9.0.35 fails (Activiti 6)

[sridharpandu]

I am trying to deploy the Activiti 6.0 WAR on Tomcat 9 using the command line on a Ubuntu VPS. I have copied the WAR file in the webapps directory when I restart Tomcat 9 it extracts the archive but the app is not accessible from the browser. I tried deploying the application from the Tomcat Web Application Manager GUI and I get an error message

Tomcat 9.0.35 Error on activiti-app deployment

These are my environment variables

My suspicion is that it is unable to complete the security configuration, Look at the line that I have highlighted. Reproducing it here

Wondering if there a way to have this resolved?
