> Kuromoji user dictionary takes Reader and allows for comments and other lines
> to be ignored. But if its "empty" in the sense of no actual entries, the
> returned FST will be null, and it will throw a confusing NPE.
> JapaneseTokenizer and JapaneseAnalyzer apis already treat null UserDictionary
> as having none at all, so I think the best fix is to fix the UserDictionary
> api from UserDictionary(Reader) to UserDictionary.open(Reader) or similar,
> and return null if the FST is empty.
