Subject [jira] [Commented] (LUCENE-3055) LUCENE-2372, LUCENE-2389 made it impossible to subclass core analyzers

Robert Muir commented on LUCENE-3055:
-------------------------------------

Chris has made a ton of progress here, I think we are very close, though it would be good
revisit LUCENE-2788 in the future and ensure that for 4.0 charfilters have a reusable API
as well (this is currently not the case).

> LUCENE-2372 and LUCENE-2389 marked all analyzers as final.  This makes ReusableAnalyzerBase
useless, and makes it impossible to subclass e.g. StandardAnalyzer to make a small modification
e.g. to tokenStream().  These issues don't indicate a new method of doing this.  The issues
don't give a reason except for design considerations, which seems a poor reason to make a
backward-incompatible change
