      The pipeline job java instances are duplicated in memory on each job-dsl execution (affecting to pipeline items modification).

      The steps to reproduce the issue are:

      • Create a freestyle job with this Process Job DSLs build step script
      freeStyleJob('dsl-free-upstream') {
    description 'FREESTYLE'
    quietPeriod(0)
    concurrentBuild(true)
    steps {
        shell 'sleep 2'
        shell 'echo "UPSTREAM"'
      shell 'echo "BYE"'
    }
}

def pscript = """
echo 'PIPELINE'
input 'Pipeline has paused and needs your input before proceeding'
node {
   echo 'inside the node'
}
echo 'BYE'
"""

workflowJob('dsl-pipeline') {
  description 'PIPELINE'
  quietPeriod(0)
  triggers {
     upstream('dsl-free-upstream', 'SUCCESS')
  }
  definition {
        cps {
            script(pscript)
        }
    }
}
      • Build the dsl job.
      • Build the dsl-free-upstream job
      • Look for that in the console output

      {{BYE
      Triggering a new build of dsl-pipeline #1
      Finished: SUCCESS}}

      • Modified the dsl job script pscript, for example:
      //...
def pscript = """
echo 'PIPELINE'
input 'Pipeline has paused and needs your input before proceeding'
node {
   echo 'inside the node'
}
echo 'BYE'
echo 'one'
"""
//...
      • Build the dsl job.
      • Build the dsl-free-upstream job
      • Look for that in the console output

      {{BYE
      Triggering a new build of dsl-pipeline #2
      Triggering a new build of dsl-pipeline #2
      Finished: SUCCESS}}

      If you add more modifications in the pipeline definition, more instances will appears.
