Odd exception (solved)

[Amir Mechouk <amir (at) lamech.se>]

Hi, in the end it was just poor coding on my part.

My application was calling FontFactory.registerDirectory on each 
generation of a pdf which resulted in a ConcurrentModificationException 
when a thread modified the fonts while another was using it.

Thanks again for a great library!

Amir
