Subject [jira] [Commented] (LUCENE-6993) Update UAX29URLEmailTokenizer TLDs to latest list, and upgrade all JFlex-based tokenizers to support Unicode 8.0

    [ https://issues.apache.org/jira/browse/LUCENE-6993?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15154936#comment-15154936

Mike Drob commented on LUCENE-6993:
-----------------------------------

Question about what is proper behaviour in terms of backwards compatibility here...

Upgrading JFlex from 1.6.0 to 1.6.1 (and 1.7.0, I assume) changes the generated output. I
have no idea if the behaviour is identical between the new class files and the old. I imagine
that we want to keep the Impls generated by the old version when operating with an old lucene
match version, rather than regenerating those with the new jflex. If so, I'll drop the work
I did on updating jflex-legacy task, since it doesn't make sense to keep around (it woudn't
generate code to match what is in source control).

Does this make sense?

> We did this once before in LUCENE-5357, but it might be time to update the list of TLDs
again. Comparing our old list with a new list indicates 800+ new domains, so it would be nice
to include them.
> Also the JFlex tokenizer grammars should be upgraded to support Unicode 8.0.
