Description David Strupl 2005-07-12 21:58:26 UTC

Hi, not sure whether this should go to pdf or loaders. Feel free to reassign.
Steps to reproduce:

NetBeans IDE Dev (Build 200507110943)

1. Open Favorites for say /tmp
2. put a temporary PDF file there (by another program not netbeans)
3. look at the favorites tab with /tmp expanded
4. make the other program (not netbeans) delete the temporary pdf file

This exception is shown to the user in the dev build:

java.io.IOException: java.lang.IllegalArgumentException: The /tmp/TK.2005.pdf
file does not exist.

Comment 1 Jaroslav Tulach 2005-07-13 08:43:16 UTC

If you are not sure, then try the same behaviour with other types of files. If   it is reproducible with only pdf, assign to that module. openide is not  trashcan for your made up issues.

Comment 2 Marian Petras 2005-07-18 11:41:07 UTC

Confirmed, accepted.

I guess this may happen if the file is deleted during the time the data loader
creates a data object for the file. I am not able to reproduce it but I believe
it may happen.

Comment 3 Marian Petras 2005-07-18 13:59:28 UTC

Fixed in the trunk.

I removed the part of code which performed the check and thrown the exception.
The check was unnecessary.

Modified files:
     utilities/src/org/netbeans/modules/pdf/:
                                      PDFOpenSupport.java   (1.12)
                                      Bundle.properties   (1.13)
