travis test failures

[mtigas]

This diff between two versions https://github.com/tabulapdf/tabula-extractor/compare/bb24fa9b98a2...f4e291c6e32a seems to have started a failing test:

bb24fa9b98a2 pass: https://travis-ci.org/tabulapdf/tabula-extractor/builds/27415350

f4e291c6e32a fail: https://travis-ci.org/tabulapdf/tabula-extractor/builds/32744778

(see history https://travis-ci.org/tabulapdf/tabula-extractor/builds )

it's literally just turning off PDFBox logging so I don't think it's a regression on our part.

i do also notice that travis-ci upgraded from jruby 1.7.11 to 1.7.13 between those two logs, so that or other pkgs being upgraded are a more likely culprit. (looks like jruby is now up to 1.7.15 on travis-ci.)

Never mind. (Thought this was about another failure.)

I've been seeing those tests fail for a very long time...
