In your first example you just use the page from the input-doc and if
you close the input-doc all resources connected to that page are lost
and finally an exception is thrown. The solution is to copy the page
before adding it to the new document. It is a little bit more
complicated than just to call a copy or clone method, but you'll find a
good example how to do that in the command line tool
org.apache.pdfbox.PDFSplit. The copy algorithm starts at
org.apache.pdfbox.util.Spliiter.split()
