Maruan Sahyoun commented on PDFBOX-4664:
----------------------------------------
Having taken another look at the current implementation COSArrayList doesn't
live up to it's documentation.
{quote}
This is an implementation of a List that will sync its contents to a COSArray.
{quote}
E.g. this constructor
{code}
public COSArrayList( List<E> actualList, COSArray cosArray )
{
actual = actualList;
array = cosArray;
}
{code}
allows to pass a List and a COSArray which is not in any way synced.
> Iterator.remove() does not work in COSArrayList

> Key: PDFBOX-4664
> URL: https://issues.apache.org/jira/browse/PDFBOX-4664
> Project: PDFBox
> Issue Type: Bug
> Affects Versions: 2.0.17
> Reporter: Zhichao Yang
> Assignee: Andreas Lehmkühler
> Priority: Minor
>
> {code:java}
> for (Iterator itr = pdfPage.getAnnotations().iterator(); itr.hasNext(); ) {
> itr.remove();
> }
> {code}
> This is not working on annotations list because cosArrayList.iterator() is
> cosArrayList.actual.iterator(), but when convert to a COSArray it uses
> cosArrayList.array, which is not affected by iterator.remove(). A iterator to
> sync the actual and the array would be nice.
