Hi guys,

I have a complex workflow with multiple stage and step (some of them run in parallel).

All worked fine until last month.

Now when I launch my job in different github branch (with a multiple pipeline job), I get the following error (not every time)

java.io.NotSerializableException: org.jenkinsci.plugins.workflow.job.WorkflowJob 

Here are steps of the stage which fails:

Stage : Start - (13 sec in block) Configuration Success

It cuts unit tests step without obvious reasons.

Do you have any idea about it ?
