We don't.  Just the "normal" dependency on a java library that's
distributed through maven central, etc.  Sorry if my wording suggested
otherwise.

AFAICT, ASL section 4d doesn't say _where_ the NOTICE content needs to
live, does it?  And we're already including a NOTICE.txt entry for
each dependency in the 'solr/licenses/' directory. [1]  Isn't the
content of 'solr/licenses/' sufficient to meet 4d?  If not, have the
majority of our deps been added incorrectly? (40ish in
solr/NOTICE.txt, ~150 in 'solr/licenses/')
