Due to lack of time and interest, I'm going to orphan pdfbox. The most recent version 1.8.5 introduces some new dependencies and I don't have the time to fix that up. The current users of pdfbox seem to be:
jabref-2.9.2-2.fc20.src.rpm solr-4.7.2-1.fc21.src.rpm tika-1.4-5.fc21.src.rpm
So hopefully one or more of those maintainers will be willing to take it on.
Thanks,
Orion
