Good morning,

I am getting the following error when trying to start a very generic setup of

Looks like you are running Tomcat on an older Java, that the app was

Ok, thanks Peter. I looked at the running.txt to see if it mentioned a Java 
version minimum and it stated Java 8, so it confused me. I'll try with Java 11.
