Uwe Schindler commented on LUCENE-3044:
---------------------------------------

Yeah fix is correct for this TokenFilter. It should loose all state on reset!

> It looks like the issue is this lazy initialization of the cloned token: if the tokenstream is reused
> and the consumer is interested in a different set of attributes, it could be a problem.
> one probably-probably-not-totally-correct fix would be to add 'clonedToken = null;' to reset(), at 
> least it would solve this case?
