> Jakarta Messaging specification version 3.1 states in chapter 
> [3.11.3|https://jakarta.ee/specifications/messaging/3.1/jakarta-messaging-spec-3.1#conversions-provided-by-streammessage-and-mapmessage]:
> "If a read method of StreamMessage or BytesMessage throws a 
> MessageFormatException or NumberFormatException, the current position of the 
> read pointer must not be incremented. A subsequent read must be capable of 
> recovering from the exception by rereading the data as a different type".
> Currently JmsBytesMessage increments the read pointer position, making it 
> impossible to reread the data after the exception.
