Weird... the NPE occurs on the following line of code:
JFileChooser fileChooser = new JFileChooser();

I'm afraid that there is not much I can do about this error. Seems to be an 
issue
with the JRE itself.

FYI

I have resolved this issue meanwhile. Apparently on my development PC the icon 
cache
was somehow corrupted. This resulted in JFileChooser being unable to access the 
"My
Computer" icon, hence the nullpointer exception. 

Best regards,
Frank
