APAR status

  • Closed as program error.

Error description

  • The WebSphere MQ Java code that calls a user supplied native
    security exit is different from the MQ C client, which may cause
    some exits to not function correctly.  The size of the
    AgentBuffer supplied by the MQ Java client to a security exit is
    zero, when the MQ C client supplies a minimum buffer size.
    
    If the exit does not check the supplied AgentBuffer size, and
    returns data in the zero length buffer, an
    IllegalArgumentException may be thrown by the MQ Java client.
    

Local fix

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    This issue affects users who have MQ Java or Java Message
    Service (JMS) applications that use native exits.
    
    Platforms affected:
    All Distributed (iSeries, all Unix and Windows) +Java
    ****************************************************************
    PROBLEM SUMMARY:
    The MQ Java client was supplying an empty buffer to the native
    exit, whereas the MQ C client supplied a buffer of a minimum
    size.
    

Problem conclusion

  • The MQ Java client has been updated to match the MQ C client
    behavior.
