Description
STEPS TO REPRODUCE
- Create an older instance of XWiki (e.g. 8.4.6)
- Close the instance
- Go to a newer instance (10.11.8) and copy/cut the
[...]webapps\xwiki
folder and replace it (first delete the old one) in the same location on the older version
- Start XWiki and follow the Distribution Wizard through the upgrade process
EXPECTED RESULTS
The upgrade process is completed successfully without errors.
ACTUAL RESULTS
After the very last step, when entering the upgraded instance, there are encountered some errors related to notifications. Stacktrace:
