Error description

  • STEPS TO REPRODUCE :
    You record messages from a client to IMS Connect using a message
    exit other than HWSSMPL1 that prefixes messages with a 4 byte
    length field (LLLL).
    
    EXPECTED RESULTS :
    You would expect to collect the IMS traffic.
    
    ACTUAL RESULTS : You see an error of type
    "NegativeArraySizeException" in the RIT proxy recording log.
    The proxy server uses only the first two bytes as the message
    length. When these two bytes are 0000, the result is a
    NegativeArraySizeException.
    This could happen when you have written you own message exits
    rather than using the provided ones. For other message exits
    than the default ones, the assumption is that the length field
    is 2 bytes followed by 2 bytes of 00's. If you make small
    modifications to HWSSMPL1, and gives the modified exit a new
    IRM-ID, the proxy server will interpret the length field
    incorrectly, eventually resulting in a
    NegativeArraySizeException.
    
    WORKAROUND :
    None
