extensions.processBean.ProcessBean event count issue

The issue is in an assertion in extensions.processBean.ProcessBeanTest, counting the number of times the Cowshed bean raises a discovery event. There are three tests affected by this issue:

extensions.processBean.ProcessBeanTest
testProcessProducerFieldEvent()
testProcessProducerMethodEvent()
extensions.processBean.ProcessSessionBeanTest
testProcessSessionBeanEvent()

specifically

testProcessProducerMethodEvent()

79: assert ProcessBeanObserver.getCowShedProcessBeanCount() == 2;

testProcessProducerFieldEvent()

102: assert ProcessBeanObserver.getChickenHutchProcessBeanCount() == 2;

testProcessSessionBeanEvent()

63: assert ProcessBeanObserver.getElephantProcessBeanCount() == 2;

But I can't see how this number is 2 instead of 1. The Cowshed looks like:

public class Cowshed {
@Produces public Cow getDaisy()

{ ... }

}

So there should be 3 relevant extension events fired:

ProcessBean<Cowshed>
ProcessProducerMethod<Cowshed, Cow>
ProcessBean<Cow>

I double checked the ProcessProducerMethod interface:

ProcessProducerMethod<T,X> extends ProcessBean<X>

which is where the ProcessBean<Cow> comes from, but I don't see where
the 2nd ProcessBean<Cowshed> comes from.

The ProcessSessionBean issue is essentially the same
