AW: How to lowercase all files with a mapper?

[apache]

Have tried that on openjdk version "17.0.1" 2021-10-19.

No warning using JavaScript on my machine.
But you also could other implementation languages for your mapper - Groovy, ... 
even Java ;-)

Adding some examples.

Can you share the script mapper with me. I would like to understand its details
