[jira] [Updated] (PDFBOX-1585)
org.apache.pdfbox.util.PDFTextStripper.getText() causes thread to block
indefinitely
[ https://issues.apache.org/jira/browse/PDFBOX-1585?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Christian Kohlschütter updated PDFBOX-1585:
-------------------------------------------
Attachment: PDFBOX-1585.patch
We had a similar problem; thanks for providing the problematic PDF.
With the help of your stack trace, it was pretty easy to figure out that pdfbox was hanging in an endless loop when reading from an InputStream that reached its end (EOF).
A patch is attached.
PS: There are some other places in pdfbox that also might loop because InputStream#read() is not checked for -1 (EOF), but this here probably is the most important one.

Hi,
we are running now with the patch and it runs fine so far.
When building pdfbox i got the following failing test:

Hi,
this is really hitting us hard on production.
Is anyone working on this already?
Maybe will try the timeout for now.
