Error description

  • V5 supports JMX 1.1 while V6 supports JMX 1.2.
    This causes incompatible difference between V5 and V6 runtimes
    and their understanding of JMX-defined objects. To help in the
    transformation of the objects special class loaders are used,
    one of which is com.ibm.ws.management.ServantMBeanStatus.
    com.ibm.ws.management.ServantMBeanStatus needs to be added to
    the list of transformed classes
    **************************************************************
    In both v5 and v6 the return object of the cluster manager
    mbeans'
    'retrieveClusters' operation is
    "com.ibm.websphere.management.wlm.ClusterData[]". But, the class
    cast exception it thrown, while trying to read that object
    (v5.1),from the SOAP message (unmarshall), in v6.1 environment.
    
    connecting to v5.1 dmgr, through wsadmin, from a v6.1
    environment; and executing the following commands,
    
    set clmgr [$AdminControl completeObjectName type=ClusterMgr,*]
    $AdminControl invoke $clmgr retrieveClusters
    
    though the return object type is same in both v5 and v6, reading
    that object from the SOAP message fails with java.lang.ClassCast
    Exception,following is the exception stack,

    This causes incompatible difference between Version 5

Problem conclusion

  • Code has been modified to avoid the ClassCastException by
    adding com.ibm.websphere.management.wlm.ClusterMemberData
    class into the list of transformed classes.
    
    The fix for this APAR is currently targeted for inclusion in
