      Description

      Xvfb cannot connect to a machine when it is enclosed inside timestamps step or option. The pipeline throws an exception:

      Also:   hudson.remoting.Channel$CallSiteStackTrace: Remote call to JNLP4-connect connection from XX.YY.ZZ.WW/XX.YY.ZZ.WW:47130
      [...]
      java.lang.IllegalAccessError: tried to access field hudson.remoting.Channel.executor from class org.jenkinsci.remoting.util.AnonymousClassWarnings
      [...]
      Caused: java.io.IOException: Remote call on JNLP4-connect connection from XX.YY.ZZ.WW/XX.YY.ZZ.WW:47130 failed
      

      I checked and the following pipelines throw exceptions:

      pipeline {
          agent {
              label 'swarm'
          }
          options {
              timestamps()
          }
          stages {
              stage('Main') {
                  steps {
                      wrap([$class: 'Xvfb']) {
                          echo 'never reached'
                      }
                  }
              }
          }
      }
      
      pipeline {
          agent {
              label 'swarm'
          }
          stages {
              stage('Main') {
                  steps {
                      timestamps {
                          wrap([$class: 'Xvfb']) {
                              echo 'never reached'
                          }
                      }
                  }
              }
          }
      }
      

      and this works correctly:

      pipeline {
          agent {
              label 'swarm'
          }
          stages {
              stage('Main') {
                  steps {
                      wrap([$class: 'Xvfb']) {
                          timestamps {
                              echo 'reached'
                          }
                      }
                  }
              }
          }
      }
