Cannot deploy Cuba application in Debian 9.6

Hi,
I am trying to deploy a cuba app in Debian 9.6 as a single WAR using Tomcat but unfortunately this is not possible. For some reason, the application does not start running. We checked the same war file in a Windows environment and it is running properly. I have uploaded the build.gradle file as well as the log file of the Tomcat server in Debian environment.CubaAppFiles.zip (12.3 KB)

I would appreciate your help since we have already spent two days to find out what is going wrong!

Thank you
