      Description

      STEPS TO REPRODUCE

      1. Create an older instance of XWiki (e.g. 8.4.6 or 11.10.5) with a subwiki
      2. Create a global user on Main Wiki
      3. Create also a local user on subwiki
      4. Close the instance
      5. Go to the newer instance (e.g. 12.5.1) and copy/cut the
        [...]webapps\xwiki

        folder and replace it (first delete the old one) in the same location on the older version

      1. Start XWiki and follow DW to the end
      2. Run also the DW for the subwiki

      EXPECTED RESULTS

      No warnings/errors are displayed.

      ACTUAL RESULTS

      After DW completes (both for Main Wiki as well as for subwiki), there are many NPE errors in console related to user mentions. Stacktrace:
