[jira] [Closed] (PDFBOX-362) ZipException occuring upon importing a page

["Tilman Hausherr (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/PDFBOX-362?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Tilman Hausherr closed PDFBOX-362.
----------------------------------
       Resolution: Invalid
    Fix Version/s:     (was: 2.0.0)
         Assignee: Tilman Hausherr

The file is definitively corrupt. The "empty" file has a lot, including a corrupt stream. But don't believe us - I just checked it with PDF-Tools
http://www.pdf-tools.com/pdf/validate-pdfa-online.aspx
and although I didn't expect it to validate, I got several errors telling the file is corrupt, including the flate-compressed stream:
{quote}Validating file "real-empty-page.pdf" for conformance level pdfa-1b
The separator after an 'obj' must be an EOL. (2)
The property 'pdf:CreationDate--Text' is not defined in schema 'Adobe PDF Schema'.
The schema description for namespace 'pdfx:' (http://ns.adobe.com/pdfx/1.3/) is missing.
The required XMP property 'pdfaid:part' is missing.
The required XMP property 'pdfaid:conformance' is missing.
The required XMP property 'xap:CreateDate' for the document information entry 'CreationDate' is missing.
Error in Flate stream: data error.
The document does not conform to the requested standard.
The file format (header, trailer, objects, xref, streams) is corrupted.
The document's meta data is either missing or inconsistent or corrupt.
