I mean no offense when I say this -- the documentation on this option
needs more clarity.  I'm also aware that this is very much a case of the
pot calling the kettle black ... Solr's documentation ALSO needs a lot
of work, and we probably have more things to fix than you.

I'm not at all surprised that it's a bug in Solr.  Thank you for
figuring this out.  Moving the option will happen with the next Solr
version.  I have confirmed that this does get rid of the warning.
