    Description

      Steps to reproduce

      1. Start XWiki (e.g. 17.10.3 and 17.10.4) on Java 25 (reproduced on both Tomcat 11 and Jetty)
      2. Observe the logs (XWiki console)

      Expected results

      No (other) warnings are displayed.

      Actual results

      The following stacktrace is displayed:
