Problem summary

  • ****************************************************************
    * USERS AFFECTED:  Users of zosConnect in IBM WebSphere        *
    *                  Application Server Liberty                  *
    ****************************************************************
    * PROBLEM DESCRIPTION: Removing and readding the zosConnect    *
    *                      feature can cause ClassCastExceptions   *
    *                      during configuration processing         *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    The metatype definitions used for processing configuration for
    the zosConnect feature are not correctly cleaned up when the
    feature is removed. This can result in configuration not being
    processed if the feature is added to the configuration again
    without restarting the server. If this happens, the logs will
    show ClassCastExceptions when the zosConnect code attempts to
    cast the unprocessed String value to a Long.
    

Problem conclusion

Temporary fix

  • If you remove the zosConnect feature, restart the server before
    adding it back again.
