[FIXED JENKINS-44330] - Prevent classloading of Target comparator in LogRecorder#orderedTargets()

It is just a hotfix, there may be other LogRecorders affected. Ideally we need a response from Jetty maintainers to https://github.com/eclipse/jetty.project/issues/1563. No tests since I see no way to trigger such classloading + no actual need in it.
