      Description

       

      The overrided methods of pipeline libraries start to loop on themselves after three iterations.

      Looks very similar to this groovy bug:

      https://issues.apache.org/jira/browse/GROOVY-6818


      Reproducing:

      pipeline library:

       

      ======== ./Order_0.groovy
      package [PACKAGE]
      import org.jenkinsci.plugins.workflow.cps.CpsFlowExecution
      import org.jenkinsci.plugins.workflow.cps.CpsThread
      
      class Order_0 implements Serializable {
          static protected def script
          def echo(Object data) {
              CpsThread thread = CpsThread.current()
              CpsFlowExecution execution = thread.execution 
              execution?.getOwner()?.getListener()?.getLogger()?.println(data)
          } 
      
          String doThingAsc () { echo '-0- (base)' }
      }
      ======== ./Order_1.groovy
      package [PACKAGE]
      class Order_1 extends Order_0 implements Serializable {
          @Override
          String doThingAsc () {
              echo '-1-'
              super.doThingAsc()
          }
          String doThingDsc () {
              echo '-1- (base)'
          }
      }
      ======== ./Order_2.groovy
      package [PACKAGE]
      class Order_2 extends Order_1 implements Serializable {
          @Override
          String doThingAsc () {
              echo '-2-'
              super.doThingAsc()
          }
          @Override
          String doThingDsc () {
              echo '-2-'
              super.doThingDsc()
          }
      }
      ======== ./Order_3.groovy
      package [PACKAGE]
      class Order_3 extends Order_2 implements Serializable {   
          @Override
          String doThingDsc () {
              echo '-3-'
              super.doThingDsc()
          }
      }
      

      pipeline file:

       

      @Library("[Library]") _;
      import [PACKAGE].*
      def test0 = new Order_0(script: this);
      def test1 = new Order_1(script: this);
      def test2 = new Order_2(script: this);
      def test3 = new Order_3(script: this);
      
      /////////////////////////////////////////
      try {
          test0.doThingAsc()
          test0.echo '-'*30
          test1.doThingAsc()
          test1.echo '-'*30
          test2.doThingAsc()
          test2.echo '-'*30
          test3.doThingAsc()
      } catch (java.lang.StackOverflowError ex) {
          echo 'We have an error ASC'
      }
      /////////////////////////////////////////
      try {
          test1.doThingDsc()
          test0.echo '-'*30
          test2.doThingDsc()
          test0.echo '-'*30
          test3.doThingDsc()
      } catch (java.lang.StackOverflowError ex) {
          echo 'We have an error DSC'
      }
      /////////////////////////////////////////

       

      We expect output:

       

      -0- (base)
      ------------------------------
      -1-
      -0- (base)
      ------------------------------
      -2-
      -1-
      -0- (base) 
      ------------------------------ 
      -2- 
      -1-
      -0- (base)
      
      
      -1- (base)
      ------------------------------
      -2-
      -1- (base)
      ------------------------------
      -3-
      -2-
      -1- (base)

       

       

       

       

       

      We get output:

      -0- (base)
      ------------------------------
      -1-
      -0- (base)
      ------------------------------
      -2-
      -1-
      -1-
      -1-
      -1-
      <... way too much ...>
      -1-
      -1-
      
      We have an error ASC
      
      
      -1- (base)
      ------------------------------
      -2-
      -1- (base)
      ------------------------------
      -3-
      -2-
      -2-
      -2-
      -2-
      -2-
      -2-
      -2-
      -2-
      -2-
      <... way too much ...>
      -2-
      -2-
      
      We have an error DSC
