/**
 * UnknnownMessageTypeException represents a failure when Mina passes an unexpected frame type.

 * <tr><td> Represents failure to cast a frame to its expected type.
 * </table>
 *
 * @todo Not an AMQP exception as no status code.
 *
 * @todo Seems like this exception was created to handle an unsafe type cast that will never happen in practice. Would
 *       be better just to leave that as a ClassCastException. However, check the framing layer catches this error
 *       first.
