The criteria workflowStep is recognized as a WorkflowStepSystemProperty.
This property add automatically the DefaultWorkflowStepEnumerator by adding the worfklow like this :

<criteria system-ref="workflowStep">
    <workflow name="program"/>
</criteria>

By default, steps greater or equals than 9000 are excluded.

If the DefaultWorkflowStepEnumerator is defined, it is overrided.

So, we shoud replace calls to DefaultWorkflowStepEnumerator in criteria workflowStep.
