                       java.lang.Throwable cause)
        Constructor with the binary data that could not be decoded, and the reason why it failed to be, and the cause. The buffer may represent the whole message, or the part of the message most relevant to the decoding error, depending whether the application is using one of the streaming methods or not.
        Parameters:
        bb - the byte buffer containing the (part of) the message that could not be decoded.
        message - the reason for the failure.
        cause - the cause of the error.
