public MBeanServerInvocationHandler(MBeanServerConnection connection,
    ObjectName objectName) 
{
        this(connection, objectName, false);
}

Invocation handler that forwards methods through an MBean server to a Standard MBean. This constructor may be called instead of relying on ObjectName, Class) JMX.newMBeanProxy , for instance if you need to supply a different ClassLoader to Proxy.newProxyInstance .

This constructor is not appropriate for an MXBean. Use #MBeanServerInvocationHandler(MBeanServerConnection, ObjectName, boolean) for that. This constructor is equivalent to {@code new MBeanServerInvocationHandler(connection, objectName, false)}.

Parameters:

connection - the MBean server connection through which all methods of a proxy using this handler will be forwarded.

objectName - the name of the MBean within the MBean server to which methods will be forwarded.

 public MBeanServerInvocationHandler(MBeanServerConnection connection,
    ObjectName objectName,
    boolean isMXBean) 
{
        if (connection == null) {
            throw new IllegalArgumentException("Null connection");
        }
        if (objectName == null) {
            throw new IllegalArgumentException("Null object name");
        }
        this.connection = connection;
        this.objectName = objectName;
        this.isMXBean = isMXBean;
}

Invocation handler that can forward methods through an MBean server to a Standard MBean or MXBean. This constructor may be called instead of relying on ObjectName, Class) JMX.newMXBeanProxy , for instance if you need to supply a different ClassLoader to Proxy.newProxyInstance .

Parameters:

connection - the MBean server connection through which all methods of a proxy using this handler will be forwarded.

objectName - the name of the MBean within the MBean server to which methods will be forwarded.

isMXBean - if true, the proxy is for an MXBean , and appropriate mappings will be applied to method parameters and return values.

Return a proxy that implements the given interface by forwarding its methods through the given MBean server to the named MBean. As of 1.6, the methods JMX#newMBeanProxy(MBeanServerConnection, ObjectName, Class) and JMX#newMBeanProxy(MBeanServerConnection, ObjectName, Class, boolean) are preferred to this method.

This method is equivalent to Proxy.newProxyInstance (interfaceClass.getClassLoader(), interfaces, handler). Here handler is the result of new objectName) , and interfaces is an array that has one element if notificationBroadcaster is false and two if it is true. The first element of interfaces is interfaceClass and the second, if present, is NotificationEmitter.class.
