Maruan Sahyoun commented on PDFBOX-5660:
----------------------------------------

[~tilman] I'd like to get rid of the Sonar warnings "Make sure this debug 
feature is deactivated before delivering the code in production." to enhance 
the rating. 

As I'm not having worked on PDFDebugger before so I likely don't understand all 
implications what do you think about
- adding an ErrorHandling class which prints to a logger as well as utilizes 
the already existing LogDialog
- add additional methods to LogDialog if necessary
- replace the e.printStackTrace(); calls with something like 
ErrorHandler.getInstance().handleException(msg, e);
