Hello,
Here is a patch to change org.apache.nutch.util.LogFormatter to not
insert itself as the default handler for the system.
I have been using Nutch for a year and have been waiting for a
version that I can embed into OpenEdit. The problem has been that
Nutch inserts itself as the formatter for the Java log system and that
interferes with OpenEdit logging.
