+ * MBean may emit an MBeanServerNotification for a group of MBeans.<br>
+ * An MBeanServerNotification emitted to denote the registration or

+ * <ul><li>Its {@linkplain Notification#getType() notification type} is
+ *     {@code "JMX.mbean.registered.group"} or

+ *     {@link
+ *     MBeanServerNotification#UNREGISTRATION_NOTIFICATION}{@code + ".group"}.

+ * <li>Its {@linkplain #getMBeanName() MBean name} is an ObjectName pattern
