Error description

  • When portlet container runtime option
    javax.portlet.actionScopedRequestAttributes is enabled, a
    NotSerializableException can appear in the SystemOut.log.
    
    This is beacuse the inner class CachedValue inside the FIFOMap
    class of Portlet Container is not declared to be serializable.
    
    Generates Exception similar to the following.
    
    WASSession    E SessionContextMBeanAdapter
    findAttCausingNotSerializableException
    Miscellaneous data: Attribute
    "javax.portlet.p.Z7_D0JM3QAH2RKHF0I3PVKQNL0013?com.ibm.ws.portle
    tcontainer.core.action_scope_cache"
    is declared to be serializable but is found to generate
    exception
    "java.io.NotSerializableException"
    with message
    "com.ibm.ws.portletcontainer.util.FIFOMap$CachedValue".

    * PROBLEM DESCRIPTION: A NotSerializableException for          *
    *                      FIFOMap$CachedValue can                 *

    * RECOMMENDATION:                                              *
    ****************************************************************
    When a portlet uses the
    javax.portlet.actionScopedRequestAttributes runtime option in
    the portlet.xml and the portlet uses request.setAttribute() to
    pass objects between lifecycle phases, you can oberve in the
    logs the following entry appearing repetitively:
    [9/12/12 11:22:26:199 EDT] 0000006f WASSession    E
    SessionContextMBeanAdapter
    findAttCausingNotSerializableException Miscellaneous data:
    Attribute
    "javax.portlet.p.Z7_D0JM3QAH2RKHF0I3PVKQNL0013?com.ibm.ws.portle
    tcontainer.core.action_scope_cache" is declared to be
    serializable but is found to generate exception
    "java.io.NotSerializableException" with message
    "com.ibm.ws.portletcontainer.util.FIFOMap$CachedValue".  Fix
    the application so that the attribute
    "javax.portlet.p.Z7_D0JM3QAH2RKHF0I3PVKQNL0013?com.ibm.ws.portle
    tcontainer.core.action_scope_cache" is correctly serializable
    at runtime.
    

Problem conclusion

  • All attributes stored in a HttpSession need to be
    serializable. Therefore changes FIFOMap$CachedValue to
    implement java.io.Serializable.
    
    The fix for this APAR is currently targeted for inclusion in
    fix pack 7.0.0.27, 8.0.0.6 and 8.5.0.2.  Please refer to the
