I have found that the Lingo3GClusteringAlgorithm will work if I copied the commons-lang-2.6.jar from the previous version to solr-8.2.0\server\solr-webapp\webapp\WEB-INF\lib.
Will this work in the long run? Because our lingo3g licence is not eligible to download the latest version of 1.16, so we are currently stuck with the older version 1.15.1, which still uses commons-lang dependency.
