Why does TomEE Plus throw a ' Can't create resource null java.lang.NullPointerException ' during start-up of a JSF 2.0 webapp?

After failing to migrate an old MyFaces 2.0 webapp (app1) from WebLogic Server 12.1.3 to Tomcat Tomcat 9 using OpenWebBeans 2.0.27 due to a potential CDI issue, I was asked to switch my attention back to TomEE Plus since this webapp also makes use of EJBs.

Irrespective of whether I use TomEE Plus 1.7.5 or 8.0.11, I get the following error at TomEE Plus start-up:

Like me, I've seen other users in SO complain about a similar pattern especially where we don't see such an error with Tomcat but only on TomEE (Plus). There seems to be no missing resource in the Axeda third-party libraries we use.

One observation is that the Maven dependency for the Oracle JDBC driver (ojdbc7-12.1.0.1.jar) needs to be of provided scope (must be added to TomEE's lib) to work which was not the case during my Tomcat trials.

Is there a known conflict with TomEE I'm missing?

I'd appreciate any input to help overcome this hurdle which has left me stranded for days now.
