/**
 * <p>Make a proxy for an MXBean in a local or remote MBean
 * Server that may also support the methods of {@link
 * NotificationEmitter}.</p>
 *
 * <p>This method behaves the same as {@link
 * #newMXBeanProxy(MBeanServerConnection, ObjectName, Class)}, but
 * additionally, if {@code notificationEmitter} is {@code
 * true}, then the MXBean is assumed to be a {@link
 * NotificationBroadcaster} or {@link NotificationEmitter} and the
 * returned proxy will implement {@link NotificationEmitter} as
 * well as {@code interfaceClass}.  A call to {@link
 * NotificationBroadcaster#addNotificationListener} on the proxy
 * will result in a call to {@link
 * MBeanServerConnection#addNotificationListener(ObjectName,
 * NotificationListener, NotificationFilter, Object)}, and
 * likewise for the other methods of {@link
 * NotificationBroadcaster} and {@link NotificationEmitter}.</p>
 *
 * @param connection the MBean server to forward to.
 * @param objectName the name of the MBean within
 * {@code connection} to forward to.
 * @param interfaceClass the MXBean interface,
 * which will also be implemented by the returned proxy.
 * @param notificationEmitter make the returned proxy
 * implement {@link NotificationEmitter} by forwarding its methods
 * via {@code connection}.
 *
 * @param <T> allows the compiler to know that if the {@code
 * interfaceClass} parameter is {@code MyMXBean.class}, for
 * example, then the return type is {@code MyMXBean}.
 *
 * @return the new proxy instance.
