Good morning.
In my job I have to create several kind of documents.
I also have a user task that allows to create a single document by
merging some (or many) of these documents.
So I create each document to merge, create and save the merged
document, close it.
After that I call PDDocument.close() on each of the original document.
Everything works fine if I merge a little number of PDDocuments (I’m
sure I call close() on each one); but if I merge many documents (and
so the procedure last a longer time), I get a warning:
Warning: You did not close a PDF Document
Hard to tell without code. You must close every PDDocument that you open
or create. Use "try with resources" if possible.
