In PDFDebugger switch to the "internal structure" view, the name tree should be
below root, it's called "Names".

If you can find where the "bad" element is, I'd love to see a screenshot.

> Class cast exception in building PDDestinationNameTreeNode

> Key: PDFBOX-5975
> URL: https://issues.apache.org/jira/browse/PDFBOX-5975
> Project: PDFBox
> Issue Type: Bug
> Affects Versions: 3.0.4 PDFBox
> Environment: Windows
> Reporter: Frans Bouwmans
> Priority: Major

> In PDDestinationNameTreeNode.java on line 63 a PDDestination is created.
> This function returns a PDDestination which is then casted to a
> PDPageDestination.
> There is however also a PDDestination of type PDNamedDestination.
> When a page is opened of a document with a named destination and the
> destination tree node is created, such as on rendering or using the splitter,
> then just opening the page will fail with a class cast exception and the page
> can therefore not be rendered, and is not included in a split document.
> A test with a check of the instance type and return null does at least fix
> the exception.
> It is not clear whether named destinations should be handled here or ignored.
