Robert Muir commented on LUCENE-2014:
-------------------------------------
Uwe, yeah the only thing modifying it should be StopFilter... so I can see the
values being "kinda strange" but not as wierd as what I see.
i worry about this clearAttributes solution though, perhaps WordTokenFilter
should use captureState/restoreState api, like the ThaiWordFilter does (very
similar analyzer).
If i use capture/restoreState this should not be a problem right?
And this way things like custom attributes would be preserved?

> If i use LUCENE_VERSION >= 2.9 with smart chinese analyzer, it will crash

> its especially annoying because it happens in 2.9.1 RC as well.
> this is because the position increments for tokens after stopwords are bogus:
> Here's an example (from test case), where the position increment should be 2,
> but is instead 91975314!
