Hi,

I have done a first fix. Wait some time until it will be available at 
the bottom of
https://repository.apache.org/content/groups/snapshots/org/apache/pdfbox/pdfbox-app/1.8.10-SNAPSHOT/
and tell me if it works, or what "bad things" happen.

Btw I still like to have a workable version of your test code. (I'm 
lazy, last time I added all the spaces myself)
