Hi,
sorry for re-posting - I am new to this list...
I am switching from lucene.net 2.0.0.4 to lucene.net 2.9.1.1 and I have
problems in a very early state.
With version 2.0.0.4 it works fine!
With version 2.9.1.1 on Microsoft it works fine
With version 2.9.1.1 on linux I always get the following errors:

>From debugging I found the reason for the errors:
dir =
Lucene.Net.Store.FSDirectory.GetDirectory(indexFileLocation, True)
and
indexWriter = New Lucene.Net.Index.IndexWriter(dirR,
analyzer, True)
but I do not have any idea what's happen here.... I have attached the
source of my test application!
Thanks for help & Regards,
Johannes
