----------------------------------

> We have some code to imitate the DissociatableManagedConnection to avoid connection leaks
that proxies connections from the supplied ManagedConnectionFactory: the proxy implements
all the interfaces of the connection, but not the class itself.  However, there's nothing
stopping the ConnectionFactory from casting the (now proxied) connection to the implementation
class it expects.
> The TxConnect project at sourceforge illustrates this approach in the EisConnectionFactory.
> http://txconnect.sourceforge.net
> One possible solution would be to have a flag to turn on this proxying behavior.  I don't
immediately see a way to detect if the problem will occur.
