That entry looks ok to me... the value would be entry 49 in the array (the next 
one) looks different to entry 47 but both are valid destination values. What I 
suspect is several string (key) entries. I was able to alter my file and 
reproduce the error. Only one line is needed if one knows the key:
{code:java}
doc.getDocumentCatalog().findNamedDestinationPage(new 
PDNamedDestination("add83"));
{code}

> 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.
