Error description

  • When you run HTTP session replication on remote eXtreme Scale
    servers, and no in-memory session cache is configured with the
    sessionTableSize=0 splicer property, the
    HttpSession.getAttributeNames() API call can return attributes
    that have no value.

    ****************************************************************
    HttpSession.getAttributeNames() returns a list of session
    attributes that are not valid.
    

Problem conclusion

  • The eXtreme Scale client code has been fixed to retrieve a
    list of session attributes so that the getAttributeNames()
    method returns only valid attributes.
