[jira] [Comment Edited] (TIKA-3718) Special PDF document causes Tika parser to hang
[ https://issues.apache.org/jira/browse/TIKA-3718?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17521236#comment-17521236 ]

----------------------------------------------------------------
It's on page 10. Probably some loop / recursion. The XObject resource looks suspicious and goes deep. PDFBox has a protection against this... and java should throw a stack overflow but nothing happens.

> Key: TIKA-3718
> URL: https://issues.apache.org/jira/browse/TIKA-3718
> Project: Tika
> Issue Type: Bug
> Components: app
> Affects Versions: 1.28.1, 2.3.0
> Environment: The problem can be reproduced under (Windows + Java8). However, the problem does not appear to be environment specific.
> Reporter: David Avant
> Priority: Major
> Attachments: map.pdf
>
>
> Attempting to parse the attached "map.pdf" causes the Tika parser to hang due to an infinite loop involving "PDFStreamParser" logic.
> This problem occurs in both tika-app 1.28.1 and 2.3.0.
> It is also worth noting that Acrobat itself will become unresponsive if attempting to open this document.
> To reproduce the problem, just run:
> java -jar tika-app-1.28.1.jar map.pdf
