Will the built-in Solr replication replicate extension JAR files in the "lib" directory? The documentation appears to indicate that only the index and any specified configuration files will be replicated, however if your solrconfig.xml references a class in a JAR file added to the lib directory then you'll need that replicated as well (otherwise the slave will encounter ClassDefNotFound exceptions). I'm wondering if I'm missing something and Solr replication will do that or if it's a deficiency in Solr's replication.
