Description
This test (https://ci.xwiki.org/job/XWiki/job/xwiki-platform/job/stable-11.8.x/3/testReport/junit/org.xwiki.test.ui/Upgrade84FileStoreTest/Platform_Builds___main___flavor_test_upgrade___Build_for_Flavor_Test___Upgrade___org_xwiki_test_ui_Upgrade84FileStoreTest/) has uncovered a potential issue when shutting down xwiki.
It seems to happen that from time to time the xwiki webapp is removed from the servlet container (jetty here) before solr has finished shutting down and thus the Jetty webapp CL is no longer available and causes the classloading issue:
