One of these might be worth experimentation, but I have less than 50% confidence that the results would compile without significant manual effort. http://codecall.net/2014/03/27/best-tools-to-convert-java-to-c-source-code/
If that were the case, you would end up on a dead-end fork of PDFBox. If one of those tools allowed you to add some rules / scripts /etc to customize its conversion so that it in fact worked for a given project, that could be quite valuable.
