   Thanks for the investigation. Upgrading Lucene is always a slight roadbump because of file format changes.
   
   All these issues will need to be in the release announcement.
   
   This would be good to pre-announce on users@jena and dev@jena and ask for feedback.
   
   Versions: IIRC (and it's been a while so caution!) `lucene-backwards-codecs` avoids the need to reload data on a major version change. Is this still true this time?
   
   JUL:
   Weird choice at this stage in the lifetime of Lucene.
   
   Use `jul-so-slf4j` - it's used elsewhere in Jena. We don't assume Log4j2 is the providing logging system - could be logback. There is no way round the potentially cyclic setup if the app wants JUL as the providing logging system - it'll have to exclude `jul-so-slf4j` itself. (This is includes one of my own projects! JUL is nice and light when you just want logging messages out.)
   
   StandardAnalyzer:
   
   Not sure whether we should set `EnglishAnalyzer.ENGLISH_STOP_WORDS_SET` in java (compatibility) or use this point in time to make the jump. `StandardAnalyzerAssembler` is impacted.
   
   Another "ask" on users@ thing.
