Regression probably caused by https://github.com/xwiki/xwiki-platform/commit/4797802e9c2b5e823180d40af2d55becb64da903#diff-2c953cc6cb981421db796f995f297e52684999203592e636607dc3bc6fa1ee12R85 done as part of XWIKI-21501: I wasn't able to reproduce the error anymore after reverting this. However, I then systematically obtained the logs from XWIKI-21855 and reverting changes done for XWIKI-21501 is probably not a good option.
