I just met the problem today, on a similar configuration, and for me, the fix
that you applied worked.

I actually just modified a bit the sample configuration for mod_deflate:

  # Don't compress images
  SetEnvIfNoCase Request_URI \
  \.(?:gif|jpe?g|png|pdf)$ no-gzip dont-vary

restarted Apache, and that was it.

In my case, the PDF file was a real, static one, not generated by a servlet.

Maybe you can have a look at the actual packets exchanged to see what is the
difference in header with and without mod_deflate?
