Andreas, I could generate the error as you describe. You can report this bug in http://issues.apache.org/jira/browse/LUCENE
There seem to be a few updates in http://snowball.tartarus.org not reflected currently in Lucene - - SnowballProgram.java has this bug fix as you describe The algorithms seem to have changed in a few of the stemmers: - DanishStemmer - EnglishStemmer - FrenchStemmer - ItalianStemmer - NorwegianStemmer - PortugueseStemmer - RussianStemmer - SpanishStemmer - SwedishStemmer Added stemmer: - HungarianStemmer Cosmetic changes: - FinishStemmer - GermanStemmer So I guess it might be worth to update all these in Lucene.
