    ****************************************************************
    A ClassCastException is generated during the recovery process
    for the ActiveMQ resource which is configured as an Isolated
    Resource Provider.
    In normal processing, all the necessary ActiveMQ classes are
    loaded by the Isolated Classloader without any problems. But
    during recovery some of the classes are loaded by the
    ExtClassLoader in addition to the IsolatedClassLoader.  The
    ClassCastException is thrown as a consequence of the
    classes being loaded by these two different class loaders.
    

Problem conclusion

  • If the resource adapter is configured as an isolated resource
    provider, only the isolated classloader is used in the
    recovery processing of the resource adapter.
    
    The fix for this APAR is currently targeted for inclusion in
    fix pack 8.5.5.13 and 9.0.0.6.  Please refer to the Recommended
