Tilman Hausherr commented on PDFBOX-3766:
-----------------------------------------
I don't have an idea for the finalize deprecation. They encourage to use
"Cleaner" but that one is only available in jdk9 so we can't use it. Many
websites tell not to use finalize() at all, but this is the only way to clean
up if the user forgets...
