Gregg,
AFAIK, arrays of a *particular* object type work just fine. The
problem described above seems to be a product of trying to hold
*arbitrary* object types in the array when the mapping informs
Castor that the array should only contain objects of type mypackage.Item.
If Castor finds that an object not of the type mypackage.Item exists
in the array, it will throw the error above.
