                                    long sequence,
                                    long timeStamp,
                                    String message,

                             throws IllegalArgumentException
        Creates a notification for either a relation creation (RelationSupport object created internally in the Relation Service, or an MBean added as a relation) or for a relation removal from the Relation Service.
        Parameters:
        notifType - type of the notification; either:

        - RELATION_BASIC_CREATION

        - RELATION_MBEAN_CREATION

        - RELATION_BASIC_REMOVAL

        - RELATION_MBEAN_REMOVAL

        sourceObj - source object, sending the notification. This is either an ObjectName or a RelationService object. In the latter case it must be the MBean emitting the notification; the MBean Server will rewrite the source to be the ObjectName under which that MBean is registered.
        sequence - sequence number to identify the notification
        timeStamp - time stamp
        message - human-readable message describing the notification
        id - relation id identifying the relation in the Relation Service
        typeName - name of the relation type
        objectName - ObjectName of the relation object if it is an MBean (null for relations internally handled by the Relation Service)
        unregMBeanList - list of ObjectNames of referenced MBeans expected to be unregistered due to relation removal (only for removal, due to CIM qualifiers, can be null)
        Throws:
        IllegalArgumentException - if:

        - no value for the notification type

        - the notification type is not RELATION_BASIC_CREATION, RELATION_MBEAN_CREATION, RELATION_BASIC_REMOVAL or RELATION_MBEAN_REMOVAL

        - no source object

        - the source object is not a Relation Service

        - no relation id

        - no relation type name
