Hi, you should also manually upgrade relevant Tika dependencies. See lucene-solr/solr/contrib/extraction/ivy.xml

When you compare changes between 1.7 and 1.12 you may find that Tika also added new dependencies such as parsers etc. Please make a list of these and suggest which of them you feel MUST be included with Solr. Note that we do not include every single Tika dependency today, to keep the distro slimmer.
