public class ObjectDecoder extends LengthFieldBasedFrameDecoder
ByteBufs into Java
objects.
Please note that the serialized form this decoder expects is not
compatible with the standard ObjectOutputStream. Please use
ObjectEncoder or ObjectEncoderOutputStream to ensure the
interoperability with this decoder.
