Subject [jira] [Updated] (TIKA-619) Error parsing GIF
Date Tue, 03 May 2011 13:21:03 GMT

     [ https://issues.apache.org/jira/browse/TIKA-619?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Alexander Chow updated TIKA-619:
--------------------------------

    Attachment: TIKA-619.patch

Can we apply the attached patch to simply ignore this exception since it is supposedly fixed
in a later version of Sun's GIFImageReader.java?  As long as we are dependent on Sun's APIs,
I am not sure if there is any other option.

> I am getting an exception parsing the following GIF file, which opens OK in firefox,
etc. Although since this is a problem in Sun/Oracle code, I would not expect it to be fixed
anytime soon!
