Error description

  • A WebSphere MQ V7 JMS application that consumes a JMS Message
    which contains a non-integer value in the Seq JMS header field
    may encounter the following exception:
    
    for input string: "" [java.lang.NumberFormatException] at:
    java.lang.NumberFormatException.forInputString

Local fix

  • Populate the empty string fields with integers when creating the
    messages.
    

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    This issue affects users of the WebSphere MQ classes for JMS,
    who are using a JMS Application to consume JMS messages whose
    RFH2 folder have been constructed by a third party application
    to contain a non-integer value for the Seq property
    
    This includes users of:
    
    - The WebSphere MQ V7.0.1, V7.1, V7.5 classes for JMS.
    - The WebSphere MQ V7.0.1, V7.1, V7.5 Resource Adapter.
    - The WebSphere Application Server V7 and V8 WebSphere MQ
    messaging provider.
    
    Platforms affected:
    All Distributed (iSeries, all Unix and Windows) +Java +Java zOS
    ****************************************************************
    PROBLEM SUMMARY:
    A JMS Message being transported by WebSphere MQ can contain
    an MQRFH2 header which carries JMS-specific data
    associated with the message.
    
    One of the folders present in an MQRFH2 header is the jms
    folder, which contains JMS header fields, and JMSX properties
    that either:
    
    i) Cannot be expressed in the MQMD header of the WebSphere
    MQ Message, or
    ii) Are duplicated from a corresponding MQMD header field
    
    When attempting to consume a message, a NumberFormatException
    was thrown if the jms folder of the MQRFH2 header associated
    with the message contained a non-integer value for the Seq
    property. This exception is thrown to the consuming application.
    

Problem conclusion

  • The WebSphere MQ classes for JMS have been updated to prevent a
    NumberFormatException being returned to an application
    attempting to consume a message when the Seq property of the jms
    folder, in the MQRFH2 header of the message, contains a
    non-integer value. In this scenario, the following error is now
    returned:
    
    "JMSCMQ1050: The MQRFH2 header has an incorrect format"
    
    ---------------------------------------------------------------
    The fix is targeted for delivery in the following PTFs:
    
    Version    Maintenance Level
    v7.0       7.0.1.12
    v7.1       7.1.0.5
    v7.5       7.5.0.3
