When upgrading from an existing index built with Lucene 8.2.0, Airsonic
fails to start with the following error:
java.lang.IllegalArgumentException: Could not load codec 'Lucene80'. Did you forget to add lucene-backward-codecs.jar?

If the library is large enough, Airsonic finishes loading the
application before the first (automatic) scan is completed. The
exception is then shown on the home page until the scan completes.
