Seems to some mix of ruby, java and javascript, and you run it through
your browser.

Last time I checked there were no 64bit java, seems there is now:

 https://www.java.com/en/download/manual.jsp

but it's 68MB for java and 53 for the source, a little big.
Does it work with any free java implementations or does it require
the latest sun/oracle one ?

Also, in the repository, there are jar files and no java source.
The pdf thing seems to be done by the java code which is binary.

So it's hard to get ideas from their code and to contribute.

 Looking at
https://source.opennews.org/en-US/articles/introducing-tabula/

they use the same intermediary format (except they also have the 
rotation parameter present) -- or used, since the mentioned ruby
script is not any longer present.

But they at least points to
 http://www.tamirhassan.com/index.html#Publications

which points to theese possible usable articles:
