      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
