Detailed Description

This class supports only the listener mechanism.

The overloaded receive methods and receiveNoWait are not implemented and throw an UnsupportedOperationException. Having both methods (receive and callback) in place causes an out of memory if the queue of message is not flushed on disk. To avoid memory neverending memory consumption I have preferred to remove the implementations of the calls leaving only the callback (given that at the present this is the only one used)
