Tilman Hausherr commented on PDFBOX-3467:
-----------------------------------------
This last change (besides breaking several tests) means that if an empty list
is returned, it cannot be modified (unless the empty list was there before),
but if a non empty list is returned, it can be modified. So a user would now
have to create an empty list if an empty list was returned and do what the
three removed lines did.
{code}
annots = new COSArray();
page.setItem(COSName.ANNOTS, annots);
retval = new COSArrayList<PDAnnotation>(new ArrayList<PDAnnotation>(), annots);
{code}
> PDPage.getAnnotations() modifies the PDF

> Project: PDFBox
> Issue Type: Bug
> Components: PDModel
> Affects Versions: 2.0.2
> Reporter: John Hewson
> Assignee: John Hewson
> Fix For: 2.1.0
>
>
> I stumbled across this bug while using PDFDebugger.
> PDPage.getAnnotations() writes to the Page's COSDictionary, adding a new
> Annots entry if it is missing.
> This violates one of the rules which we introduced for 2.0, that reading from
> a PDF file should not result in the file's COS model being modified.
