> Using interface proxies together with polymorphism can lead to sporadic ClassCastExceptions.
> This problem occurs whenever two mapped subclasses have an identical property and the instances are loaded polymorphically through the base class.
> The attached testcase and mapping file can be used to reproduce the problem. You may need to run the test case a couple of times to reproduce the error --- depending on the order in which the proxy factory iterates through the sub-interfaces, the test succeeds or yields an error.
