Michael McCandless commented on LUCENE-1678:
--------------------------------------------
bq. The way Lucene stuff generally goes, if someone like Grant or Mike really
wanted to push changes, the changes would happen.
Well, it's consensus that we all need to reach (at least enough
consensus to vote on it), and on complex topics it's not easy to get
to consensus.
bq. Giving up is really not the answer though - thats why the discussion has
come and gone in the past.
I don't think anyone has given up. The issue still smoulders and
flares up here and there (like, this issue). Eventually we'll get
enough consensus for something concrete to change.
bq. I have no moral right to hammer my ideals into heads that did tremendously
more for the project, than I did.
In fact you do & should. This is exactly how change happens. Here's
a great (though sexist) quote:
"The reasonable man adapts himself to the world; the unreasonable one persists
to adapt the world to himself. Therefore all progress depends on the
unreasonable man." - George Bernard Shaw

> Key: LUCENE-1678
> URL: https://issues.apache.org/jira/browse/LUCENE-1678
> Project: Lucene - Java
> Issue Type: Bug
> Components: Analysis
> Reporter: Michael McCandless
> Assignee: Michael McCandless
> Priority: Minor
> Fix For: 2.9
>
>
> The addition of reusableTokenStream to the core analyzers unfortunately broke
> back compat of external subclasses:
>
> http://www.nabble.com/Extending-StandardAnalyzer-considered-harmful-td23863822.html
> On upgrading, such subclasses would silently not be used anymore, since
> Lucene's indexing invokes reusableTokenStream.
> I think we should should at least deprecate Analyzer.tokenStream, today, so
> that users see deprecation warnings if their classes override this method.
> But going forward when we want to change the API of core classes that are
> extended, I think we have to introduce entirely new classes, to keep back
> compatibility.
