Cannot start app server in 19.1

I'm upgrading appian from 18.3 to 19.1 and have made all required changes however when i try to start the appserver it creates a new folder in the default appian log directory called "tomcat" but there are no logs in that folder.  Previous release did have tomcat-stdout.log file that contained logs for the tomcat server has any one else run into this issue?
