The method it's complaining about not being there is org.apache.solr.core.SolrCore.getLatestSchema() ... which is in Solr itself, not the dataimport handler. I did some checking. This method did not exist before 4.4.0, so my best guess is that your classloader is loading a SolrCore class from 4.3.1 or earlier, which probably means one of two things: 1) The Solr war you're extracting is not actually version 4.6.0, or 2) you've got jars in your system from one or more older versions. It's a good idea to delete the extracted war data whenever you upgrade Solr -- stop the container, delete the extracted data and all old jars, then replace the .war file and start it back up.
