Subject [jira] [Created] (JSPWIKI-721) Log FileNotFoundException on missing attachment
Date Tue, 21 Feb 2012 13:44:34 GMT
Log FileNotFoundException on missing attachment

                 Key: JSPWIKI-721
             Project: JSPWiki
          Issue Type: Improvement
          Components: Core & storage
    Affects Versions: 2.8.4
            Reporter: Jürgen Weber
            Priority: Minor

We messed with the repository and had an attachment folder without the actual attachment.
This results in a FileNotFoundException in
BasicAttachmentProvider.getAttachmentInfo(WikiPage, String, int)
and comes up as the infamous 
java.lang.IllegalArgumentException: Attempt to provide a null filter - this should never happen.
 Please check your configuration (or if you're a developer, check your own code.)
        at com.ecyrd.jspwiki.filters.FilterManager.addPageFilter(

A log in the FileNotFoundException catch block would help a lot:

   catch( FileNotFoundException e )
            log.error("Can't get attachment properties for "+att, e );
            return null;
