Reported by @jeremybmerrill in tabulapdf/tabula#707:

I'm getting empty responses on a PDF that should work (and do work off of master) from this.
For several different selections that work on master, I get this response for each, regardless of the extraction method I choose: [{"extraction_method":"","top":0.0,"left":0.0,"width":0.0,"height":0.0,"data":[[{"top":0.0,"left":0.0,"width":0.0,"height":0.0,"text":""}]], "spec_index": 0}]. The params to the request look right (and do work right, as I said, on master).
