[jira] [Commented] (PDFBOX-1088) Class PDDocument Method getPageMap returns a ClassCastException

["Maruan Sahyoun (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/PDFBOX-1088?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13102728#comment-13102728 ] 

Maruan Sahyoun commented on PDFBOX-1088:
----------------------------------------

The issue was introduced in rev. 1092855 by changing the line in the method processListOfPageReferences

from
COSArray pageArray = ((COSArrayList)(((PDPage)pageOrArray).getParent()).getKids()).toList();

to
List pageArray = ((((PDPage)pageOrArray).getParent()).getKids());

For the newer version the next line 

parseCatalogObject((COSObject)pageArray.get(i)); will fail as get will return a PDPage where for the original version it will return a COSObject.

I'll submit a patch to revert to the original version.
