Subject [jira] Resolved: (PDFBOX-455) java.lang.ClassCastException: org.pdfbox.cos.COSString cannot be cast to org.pdfbox.cos.COSName
Date Fri, 03 Jul 2009 14:50:47 GMT

     [ https://issues.apache.org/jira/browse/PDFBOX-455?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Andreas Lehmkühler resolved PDFBOX-455.
---------------------------------------

       Resolution: Fixed
    Fix Version/s: 0.8.0-incubator

With version 790931 I've added some type checks. As an enhancement to Seans suggestion I've
added the code to all getter of simple datatypes like int, long, string, float and boolean.
