Hello and happy new year! Indeed reverting back to 'class' attribute in place of 'name' did the trick, now I don't see any nullpointerexception anymore.
Thank you! Please let me know if I should fill in a bug report. this is my stopwords.txt in conf folder, that I think is just the default: # Licensed to the Apache Software Foundation (ASF) under one or more # contributor license agreements.

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.
