| Description: |
The following exception is often seen (not 100%) while filtering confluence packages using the output instance filter twice . The attached package has a good reproduction rate.
Reproduction steps:
* # Install the Filter Streams Converter extension
* # Install the Confluence-XML extension
* # Go to [ http://localhost:8080/xwiki/bin/view/Filter/ ]
** Input type: Confluence XML input filter stream (confluence+xml)
*** source: the attached file
** Output type: XWiki instance output stream (xwiki+instance)
# Run the migration
# repeat 3 and 4.
This happens when the filter overwrites attachments that already exist.
