    Description

      Preconditions: Have Java 11.0.3 installed and running.

      When starting a local instance of XWiki 11.5, some warnings are displayed in console:

      WARNING: An illegal reflective access operation has occurred
WARNING: Illegal reflective access by com.thoughtworks.xstream.core.util.Fields (file:/C:/ILIE%20LUCRU/XWIKI%2011.4/xwiki-platform-distribution-flavor-jetty-hsqldb-11.4%20STD%20JAVA%208/webapps/xwiki/WEB-INF/lib/xstream-1.4.11.1.jar) to field java.util.TreeMap.comparator
WARNING: Please consider reporting this to the maintainers of com.thoughtworks.xstream.core.util.Fields
WARNING: Use --illegal-access=warn to enable warnings of further illegal reflective access operations
WARNING: All illegal access operations will be denied in a future release

      The warnings are not recorded in the log.

      I've tested and reproduced the issue also on XWiki 11.4 and 11.3.
