Tilman Hausherr commented on PDFBOX-4109:
-----------------------------------------
[~jesmith3] does the deadlock happen in your production code, or were you just
trying to find some easy way to reproduce a closed issue? I looked at the test
code and from what I see, it can only work if {{PDDocument}} isn't initialized
first. Which would be unusual IMHO.
