Xvfb does not work when wrap([$class: 'Xvfb']) is defined inside timestamps

Issue Type:	Bug
Assignee:	Steven G Brown
Attachments:	Jenkins Master.html, Jenkins Slave.html, stacktrace.txt
Components:	timestamper-plugin, xvfb-plugin
Created:	2019-02-01 10:21
Environment:	Jenkins: 2.150.1 Xvfb: 1.1.3 timestamper: 1.8.10 See more in Jenkins Master.html and Jenkins Slave.html files
Priority:	Major
Reporter:	Adam Gabryś

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

[...]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'
                    }
                }
            }
        }
    }
}

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

Re: Xvfb does not work when wrap([$class: 'Xvfb']) is defined inside timestamps

We started using a new feature introduced in the [Timestamper|https://plugins.jenkins.io/timestamper/] 1.9 plugin: Enable for all Pipeline builds. The timestamps are printed correctly.
