Error description

  • When using eXtreme Scale for HTTP session replication, session
    attributes of type, HttpSessionBindingListener, might not be
    called back correctly when the session is invalidated,
    specifically when the valueUnbound method is called. This can
    only happen after an application server failure, a loss of
    affinity, or if the sessionTableSize limit is exceeded for
    in-memory sessions.

    Session attributes of type, HttpSessionBindingListener,
    might not be called back correctly when the session is
    invalidated, specifically when the valueUnbound method is
    called.
    

Problem conclusion

  • The eXtreme Scale client code has been fixed to make the
    appropriate valueUnbound callback when the session is
    invalidated or when the HttpSessionBindingListener attribute
    is
    removed.
