Very mysterious. I searched into the tabula sources for "swing" and
"awt" and didn't find anything that opens a window.
PDFBox build tests open a window.

Hello there,
I have a small issue with PDFBox that I'm trying to resolve and could
use some assistance. Here's my use case: I'm trying to add the
capability to Apache Drill to be able to read and query tables
contained in PDF files. I am using pdfbox 2.0.25 and Tabula 1.0.5.
Here's a link to the full pull request:
https://github.com/apache/drill/pull/2359
That's a lot of code and it is hard to find the relevant PDFBox code.
It looks like you are using PDFBox to load the PDF and Tabula to do
some magic, aren't you?
While everything in the code works quite well, when I actually open
the file for reading it appears that pdfbox opens an empty Java
window. The only way I've found to prevent this is to add:
PDFBox doesn't open any windows as long as you don't use PDFDebugger ;-)
System.setProperty("java.awt.headless", "true");
to my code right before the PDDocument is opened. Unfortunately, my
PR will not be accepted with this, so I'm wondering if there is any
way to prevent this window from being opened? Any advice would be
greatly appreciated.
If it is opened BEFORE calling any PDFBox code it likely is some
static code executed when loading some classes. But again, PDFBox
doesn't do anything like that. Maybe some Tabula code?
Thanks!
