[jira] [Comment Edited] (PDFBOX-5278) PDPage.getAnnotations()
causes subsequent calls to PDDocument.getPages() to fail
[ https://issues.apache.org/jira/browse/PDFBOX-5278?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17412115#comment-17412115 ]

------------------------------------------------------------------
[~mkl] Your suspicion is correct :-)
[~alistairo] Your files are a mess. For example, the "64" file has a annotation 31 on page 7 referencing not an annotation directory, but page 1. Look for "43 0 R" and "43 0 obj" with notepad++ in that file.

> Key: PDFBOX-5278
> URL: https://issues.apache.org/jira/browse/PDFBOX-5278
> Project: PDFBox
> Issue Type: Bug
> Components: Text extraction
> Affects Versions: 2.0.24
> Reporter: Alistair Oldfield
> Priority: Major
>
> I have stumbled across a strange issue with a certain PDF where PDPage.getAnnotations() causes subsequent calls to PDDocument.getPages() to fail.
>
> I am not at liberty to share the PDF publicly, but am happy to DM the PDF privately if it helps.
>
> The code to reproduce is pretty straightforward:
>
>
> {code:java}
> import java.io.File;
> import org.apache.pdfbox.pdmodel.PDDocument;
> import org.apache.pdfbox.pdmodel.PDPage;
> public class AnnotationsTest {
>
> public static void main(String[] args) throws Exception {
>
>
> try( PDDocument doc = PDDocument.load(new File(args[0]));){
> for (PDPage page : doc.getPages()) {
> //this line will cause the doc to not be re-iterable in the next block, commenting it out will allow it to pass.
> page.getAnnotations();
> }
>
> System.out.println("We get here, no problem - not sure why we can't re-iterate again...");
>
> //doc.getPages() fails.
> for (PDPage page : doc.getPages()) {
> //do something
>
> }
> }
> }
> {code}
> The Exception:
>
> Exception in thread "main" java.lang.IllegalStateException: Expected 'Page' but found COSName\{Annot}Exception in thread "main" java.lang.IllegalStateException: Expected 'Page' but found COSName\{Annot} at org.apache.pdfbox.pdmodel.PDPageTree.sanitizeType(PDPageTree.java:266) at org.apache.pdfbox.pdmodel.PDPageTree.access$400(PDPageTree.java:43) at org.apache.pdfbox.pdmodel.PDPageTree$PageIterator.next(PDPageTree.java:224) at org.apache.pdfbox.pdmodel.PDPageTree$PageIterator.next(PDPageTree.java:172) at AnnotationsTest.main(AnnotationsTest.java:28)
