FileNotFoundException, is this code supposed to work?

[Simon Gartz]

Hi,

I've seen this questions before with slightly different approaches, but
non with sample code. Is this code supposed to work or not, using
Lucene.net v1.9.1.3?
I get follwing error executing the code below. Note that it might take
some time to crash.

System.IO.FileNotFoundException : Could not find file
