Uwe Schindler commented on LUCENE-1636:
---------------------------------------
bq. A good example of this 'abuse' is in ShingleMatrixFilter.java in one of
it's constructors.
This class extends TokenStream not TokenFilter! As the input instance member of
TokenFilter is now final, it would not even compile. Please note, this is one
of the contrib packages, not yet using the new API, so with useNewApi set to
true, this TokenStream would fail (see LUCENE-1460). The change, you have the
problem with, is caused by the new TokenStream API, and so NULL delegates are
not possible!
> TokenFilters with a null value in the constructor fail

> Key: LUCENE-1636

> Project: Lucene - Java
> Issue Type: Bug
> Affects Versions: 2.9
> Reporter: Wouter Heijke

> Fix For: 2.9

> Attachments: LUCENE-1636.patch

>
> While migrating from 2.4.x to 2.9-dev I found a lot of failing unittests.
> One problem is with TokenFilters that do a super(null) in the constructor.
> I fixed it by changing the constructor to super(new EmptyTokenStream())
> This will cause problems and frustration to others while migrating to 2.9.
