I have used this class for multiple events, but the only thing I verify on
the mock listener at that moment is the number of events received, not the
actual data of each event.

Tell me if my thoughts match yours: the MockPropertyChangeListener maintains
a list of EventMatch objects, in the order I expect each event. When I add
an EventMatch object to the mock listener, the EventMatch object contains a
fully configured PropertyChangeEvent as the expected event. When the
propertyChangeEvent on the mock listener is invoked, it takes the actual
event and pushes it to the EventMatch object, increments the eventCount
expectation. A subsequent call will push the actual event to the next
EventMatch object in the list. Verification of the mock listener also
invokes the verificiation on the EventMatch objects.

If this is your idea, can't a similar thing be done with an
ExpectationCollection? Initially pushing the expected PropertyChangeEvent
objects as expected values and then collecting the actual values?
