Hi, It is indeed an empty (null) stopwords "CharArraySet" being passed in https://github.com/apache/lucene/blob/branch_9_8/lucene/core/src/java/org/apache/lucene/analysis/StopFilter.java#L39
If you flip back to class="solr.StopFilterFactory", does it work then? Does your stopwords.txt file contain any stopwords or is the file empty? There may be subtle difference in classloader / resourceLoader behavior when loaded with "class" vs "name", if so this is likely a bug to be investigated.
