Summary:
A Declarative Jenkinsfile which is using a Library that has a syntax error in it can create a NotSerializableException.

Prerequisites:
1. A repo with a shared library, in the form of repo-name/blob/master/vars/Variables.groovy. The library needs to be bugged. I used this (note the parenthesis ( ) around the values for agentNames[] instead of square brackets [ ]:

/* 
Use these with your declarative pipelines.
*/

// Let's insert this purposely bugged String array, to  see if 
// Jenkins picks up the library at all.
String[] agentNames = ("linux","windows","other")
int FILE_SIZE = 3333
// String FILE_SIZE = "4444"

2. This shared library needs to be set up in /configure, under Global Pipeline Libraries:

3. A Jenkinsfile that makes use of this shared library (I'll attach the one I've used). I've been able to recreate this both as a mulibranch pipeline job from a GitHub Enterprise repo, and as a standalone Pipeline job.

Steps to recreate:
1. Create your job with the following Jenkinsfile:

pipeline {

    libraries {
        lib("declarative-libs")
    }

    agent {
        label ("linux")
    }

    stages {
        stage('Set file size with a shared lib, WOW') {
            steps {
                echo "--> SIZE_OF_GIBBERISH_FILE is ${Variables.SIZE_OF_GIBBERISH_FILE}"
                script {
                    int randomFileSize = "${Variables.SIZE_OF_GIBBERISH_FILE}"
                    stage ("Script stage") {
                        for (int j = 0; j < 5; j++) {
                            node {
                                sh "for i in `seq 1 100`; do cat /dev/urandom | env LC_CTYPE=c tr -dc \'[:alpha:]\' | head -c $randomFileSize; done"
                            }
                        }
                    }
                }                      
            }
        }
    } // end stages
 }

2. Run the build.

3. Observe a NotSerializableException in the console output:

Description

Original: *Summary:*
A Declarative Jenkinsfile which is using a Library that has a syntax error in it can create a NotSerializableException.

*Prerequisites:*
1. A repo with a shared library, in the form of {{repo-name/blob/master/vars/Variables.groovy}}. The library needs to be bugged. I used this:

{code:none}
/*
Use these with your declarative pipelines.
*/

// Let's insert this purposely bugged String array, to see if
// Jenkins picks up the library at all.
String[] agentNames = ("linux","windows","other")
int FILE_SIZE = 3333
// String FILE_SIZE = "4444"

{code}

2. This shared library needs to be set up in /configure, under Global Pipeline Libraries:

!image-2017-09-06-21-03-06-958.png|thumbnail!

3. A Jenkinsfile that makes use of this shared library (I'll attach the one I've used). I've been able to recreate this both as a mulibranch pipeline job from a GitHub Enterprise repo, and as a standalone Pipeline job.

*Steps to recreate:*
1. Create your job with the following Jenkinsfile:

{code:none}
pipeline {

    libraries {
        lib("declarative-libs")
    }

    agent {
        label ("linux")
    }

    stages {
        stage('Set file size with a shared lib, WOW') {
            steps {
                echo "--> SIZE_OF_GIBBERISH_FILE is ${Variables.SIZE_OF_GIBBERISH_FILE}"
                script {
                    int randomFileSize = "${Variables.SIZE_OF_GIBBERISH_FILE}"
                    stage ("Script stage") {
                        for (int j = 0; j < 5; j++) {
                            node {
                                sh "for i in `seq 1 100`; do cat /dev/urandom | env LC_CTYPE=c tr -dc \'[:alpha:]\' | head -c $randomFileSize; done"
                            }
                        }
                    }
                }
            }
        }
    } // end stages
}
{code}

2. Run the build.

3. Observe a NotSerializableException in the console output:
