[valueDescription : String, expectedSourceBean : Object, expectedPropertyName : String, expectedValueType : Class<?>, nullIsValid : Boolean]:

1. valueDescription

   The conventional value description.

2. expectedSourceBean

   The JavaBean that is the expected source of the PropertyChangeEvent.

3. expectedPropertyName

   The property expected to be described by the PropertyChangeEvent.

4. expectedValueType

   The expected type of the new property value.

5. nullIsValidValue

   true or false depending on whether null is a valid value or not, respectively.
