Christopher Currens closed LUCENENET-179.
-----------------------------------------
Resolution: Invalid
It's been so long since this patch was submitted (2009), that it's no longer
needed. The new version of the SnowballFilter from 3.0.3 only uses reflection
in the constructor to create the filter (as does the patch). It's too bad this
didn't make it into 2.9.4, where it could have really been used.

> I'm using Lucene.Net along with snowball stemming to index text from a
> database. The class Lucene.Net.Analysis.Snowball.SnowballFilter uses the
> reflection API and the invoke method to call the stem methods of snowball. I
> have written a Snowball filter which creates a delegate and uses this
> delegate to stem the words afterwards. This approach improves the indexing
> speed of my indexing program by about 10%. I would be happy if you include
> this code into lucene.net.
