PdfComparator.compare() was called.

Just calling new PDDocument(); in begin of main() solves this problem.

No idea. So did I understand your second comment correctly, that you fixed the problem? Then I can close this ticket?

SoltauFintel commented 4 years ago

I will research this a little further, report here and then close the ticket. Other users could also encounter this error. Funnily enough, my JUnit test worked, but it didn't work in the productive Swing app. Could you please write something about my other ticket.

I haven't found a better solution than calling new PDDocument() at the beginning of main().
