Review Comment:
While it is great that this is forward ported to the latest versions of 8,11
and 17, there is still the issue of people running with older versions of the
JDK and can not change. So it would be nice to have a bit more logic in there.
@EwoutH I saw your comment; sorry I am pretty swamped right now to work on
this change beyond this initial PR.
> JDK 21 throws annotations processing warning that can not be turned off

> maven compiler plugin 3.11 on Java 21 reports
> {quote}
> [INFO] Annotation processing is enabled because one or more processors were
> found
> on the class path. A future release of javac may disable annotation
> processing
> unless at least one processor is specified by name (-processor), or a search
> path is specified (--processor-path, --processor-module-path), or annotation
> processing is enabled explicitly (-proc:only, -proc:full).
> Use -Xlint:-options to suppress this message.
> Use -proc:none to disable annotation processing.
> {quote}
> However, the {{<proc>}} option only supports "none" and "proc", not "full"
> (which is the implicit default).
> Adding this through a compiler option:
> {quote}
> <configuration>
> <compilerArgs>
> <arg>-proc:full</arg>
> </compilerArgs>
> </configuration>
> {quote}
> fixes this warning. Adding "full" as a value for the compiler plugin would
> fix it, too.
