If I set the writer to binary on 5.4.1, it fails too. My intent when I wrote the program was to use the binary writer, but apparently I didn't actually implement that. 5.4.1 works with the default (xml) writer. I have not tried 5.5 with the xml writer, but I bet that would work. I just added a null check to the part of my code that does doc.addField, skipping the add if the object is null. This appears to have fixed the problem when using SolrJ 5.5. This is also a good idea for my program in general, so I'm not really unhappy about needing it. So, I believe what happens with the binary writer is that when the field contains a null object, the writer is adding the literal string "NULL" (in uppercase) as the field value. The XML writer apparently handles this situation by not including the field. Thanks, Shawn
