I wish this was an NPE.  It would be easier to track down.

There is no proxy.  Although I do have a load balancer (haproxy) in
place for queries, this program doesn't use it.

It looks to me like SolrJ 5.5 behaves in a way that changes what gets
sent when talking to an existing Solr install using the default Jetty
config.  This seems like a bug to me.

I need to investigate what happens in my code when MySQL returns NULL
values.  I suspect that the object assigned to the SolrInputDocument
field is null.  Whatever it is that happens, SolrJ 5.4.1 works correctly
and 5.5.0 doesn't.
