On the last run, it only failed to index ONE batch.  30287 successful 
POST requests and ONE failure.  That failure was the same as what I have 
already reported -- "HTTP protocol violation: Authentication challenge 
without WWW-Authenticate header".

It doesn't seem likely that this is a problem with Solr-specific code in 
either Solr or SolrJ, but I don't really understand what's going on, so 
I am not going to claim that this analysis is correct.

Can anyone shed a little light on this and suggest additional info I can 
gather?  I have full control over logging levels with my logback config. 
 I have already reduced the logging level for org.eclipse.jetty to WARN 
because it was REALLY noisy.  The root logger is at DEBUG so I can use 
that logging level in my own code, so I had a few loggers to turn down. ;)

I commented the line setting org.eclipse.jetty to WARN, and I'm running 
it again.  This is going to create a VERY big logfile, because jetty is 
now logging at DEBUG.

Thanks,
Shawn
