             Summary: Document.save() after Document.close() causes Null 
Pointer Exception
                 Key: PDFBOX-1926
                 URL: https://issues.apache.org/jira/browse/PDFBOX-1926
             Project: PDFBox
          Issue Type: Bug
    Affects Versions: 1.8.4
         Environment: Linux (Ubuntu)
            Reporter: Bastian Preindl


Until version 1.8.3 it was possible to perform a document's save()-call also if 
the document's close()-method has already been called. In my opinion this made 
sense as I'd like to persist the document's content also if no more (content 
changing) operations are performed on it.

Anyway, in 1.8.4, calling save() after close() causes a NullPointerException:

Caused by: java.lang.NullPointerException
        at 
org.apache.pdfbox.pdmodel.PDDocument.getDocumentCatalog(PDDocument.java:765)
        at org.apache.pdfbox.pdmodel.PDDocument.save(PDDocument.java:1346)
