Description
STEPS TO REPRODUCE
Preconditions: An older instance of XWiki (e.g. 8.4.6) and an instance of XWiki 10.10 (to which will be migrated) are available.
- Login to the older instance
- Create a new subwiki
- Close the instance
- Go to the newer instance (10.10) 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
- Go to Wiki Index and click on the previously created subwiki's name to run the DW
EXPECTED RESULTS
The upgrade process is completed successfully without errors both on the Main wiki, as well as on subwiki.
ACTUAL RESULTS
Before starting the DW for the Main Wiki (when XWiki is initializing to app. 24% in browser), some errors are encountered in console and the initializing process is greatly delayed. Stacktrace:

However, the DW process finishes eventually. Sometimes, also the following error is displayed in console (ILIE is Admin user):

Please find attached the logs containing the errors. The issue was reproduced on MySQL 5.7, PostgreSQL 10, Oracle 11.2 and HSQL 2.4.1 (using various browsers).
