Suggest a fix/enhancement

... elaborating best answer, docs and testing.... :

Downgrading maven-compiler plugin (to maximum version 3.5.1) seems the only choice to stay "backward compatible"... which raises further issues (maven.compiler.source ...)
Documenting "Jdk >= 9" (or even 11/17 and upgrading maven-compiler) is the other option.

Please discuss/fix
