Hello all,
I have an issue in migrating my core from solr 8.11 to 9.4.
I readed the changes
https://github.com/apache/solr/blob/main/solr/solr-ref-guide/modules/upgrade-notes/pages/major-changes-in-solr-9.adoc
And basically did the following:
* solrconfig.xml: removed <lib> tags pointing to a wrong path, changed
FastLRUCache to CaffeineCache, changed luceneversion to 9.8.0
* schema.xml: replaced <tokenizer> class attribute to name attribute
whenever possible, the same for <filter>
I don't see any other changes I need to make,
still when I try to load my core I see in solr log

It looks like it can't find a very basic class, should I add something in <lib>
?
I tried to create a new core, that starts correctly without any <lib> entry in
solrconfig.xml
Thank you for your help!
