      Using load step to load two different groovy files without an explicit class but the same package declaration, causes Jenkins to fail during startup process if the build should be resumed.

      For example, create a dummy pipeline like

      def util
def config
def util2

node('master') {
    sh 'cp -r /tmp/test/src .'

    config = load 'src/org/foo/devops/JenkinsEnvironment.groovy'
    util = load 'src/org/foo/devops/Utility.groovy'

    config.loadProdConfiguration()    
}
util.isValueExist("")

echo "kill me while I'm sleeping"
sleep 20

node('master') {
    util2 = load 'src/org/foo/devops/Utility.groovy'
    util = load 'src/org/foo/devops/Utility.groovy'
}

      And copy the two attached files at /tmp/test/src/org/foo/devops/
      (Files can be retrieved as you prefer)

      Build the job and restart jenkins while is building.

      Then you won't be able to access Jenkins.
