----------------------------------------
Attachment: NUTCH-1521-trunk.patch
Hi Lufeng, I attach a unified patch for your code which I've tested locally and
would like to commit. I added a brief class description and formatted it as per
the Nutch project formatting.
You indicated in the issue description that you may want to add some WARN
logging... this is up to you.
Are you able to provide a similar patch for trunk?
Thank you for the contribution and good catch!
