That needs Java, which I am definitely not going to re-install (smile).

OpenOffice was notorious for legacy bloat, so that would make sense.
LO devs have managed to remove a large amount of useless code.

My file has  14 pp  of simple text.  I've now uploaded the files above
& everyone can inspect them & their structure at

  http://www.chass.utoronto.ca/~purslow/test/

I've renamed the PDFs to show their origin, ie LibreOffice + Ghostscript.
Perhaps that will allow others to investigate.

I will also have a look at Cups-pdf & at Willie Wong's suggestions.

PS the file is a list of books I've noted as worth reading,
so it may have a wider (OT) interest than simply to solve this problem.
