             Summary: 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


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.
