Problem with partial content 1.7.4

I was having trouble loading partial content after upgrading nginx to 1.7.4. I didn't realize it might be nginx until I compared the headers on my dev system which uses nginx 1.6.0 and my production system which uses 1.7.4 (I know, they should be equal).

Behind nginx there is a Tomcat 7/Spring MVC server

On 1.7.4 it looks like only the first partial receives the accept-ranges:bytes but subsequent do not

On the same pdf file that is requested I see the following

1.6.0

I would also like to reference this discussion
https://www.ruby-forum.com/topic/5024940

Is this a bug or is it something I might be related to the Spring/Tomcat setup?
