JENKINS-67173 proposes the removal of support of agent-to-controller FilePath access.

https://github.com/jenkinsci/genexus-plugin/blob/3b717c0a55e516ccf65648f227beba46482e68a2/src/main/java/org/jenkinsci/plugins/genexus/server/CreateLogTask.java#L105 implements that by calling a method of a controller FilePath from a MasterToSlaveFileCallable. This code should be restructured for compatibility.
