Question
Hi Folks! Another wild and crazy question.
So, Tomcat 10.0.2. I see that it uses Jakarta EE 9, and the README states it requires at least Java 8. So, will it run just fine on Java 1.8x or does the Jakarta EE 1.9 have to be installed?
Thanks,

You only need Java 8.
There is no such thing as Jakarta EE 1.9.
Jakarta EE 9 is a collection of APIs and specifications for how those
APIs are expected to behave. Tomcat implements a subset of those
specifications and APIs (Servlet, WebSocket, EL, Server Pages,
Authentication and Annotations).
Note that you cannot take an application that works on Tomcat 9 and use
it unchanged on Tomcat 10 because in the move from Java EE 8 (Tomcat 9)
to Jakarta EE 9 (Tomcat 10) the java package name used by all the APIs
changed from javax... to jakarta...
The Tomcat community has provided a migration tool that converts
applications from Java EE 8 to Jakarta EE 9:
