QuickFIXJ MBeanServerInvocationHandler.newProxyInstance参数类型错误

Question

在为QFJ构建JMX客户端服务时，我在使用不同的MBean接口时遇到错误。我需要调用ConnectorAdminMBean中的方法，但它不能绑定到SessionAdminMBean的方法。抛出的错误：

newProxyInstance() in MBeanServerInvocationHandler cannot be applied to: 
interfaceClass: (Expected) java.lang.Class<T> | (Actual) ConnectorAdminMBean.class

方法：

public static <T> T newProxyInstance(MBeanServerConnection connection,
                                         ObjectName objectName,
                                         Class<T> interfaceClass,
                                         boolean notificationBroadcaster) {
        return JMX.newMBeanProxy(connection, objectName, interfaceClass, notificationBroadcaster);
    }

这已经证实是有效的：

ObjectName mBeanBLBG = new ObjectName("org.quickfixj:type=Session,beginString=FIX.4.2,senderCompID=SCB,targetCompID=BLBG");
SessionAdminMBean mBeanBLBGProxy = MBeanServerInvocationHandler.newProxyInstance(jmxConnectionInstance.getmBeanServerConnection(), mBeanBLBG, SessionAdminMBean.class, true);

然而，当我尝试这样做时，它抛出了一个错误，即第三个参数是错误的：

ObjectName mBeanConnector = new ObjectName("org.quickfixj:type=Connector,role=Initiator,id=1");
SessionAdminMBean mBeanConnectorProxy = MBeanServerInvocationHandler.newProxyInstance(jmxConnectionInstance.getmBeanServerConnection(), mBeanConnector, ConnectorAdminMBean.class, true);

我已经查看了各自的接口，但没有看到任何区别。

package org.quickfixj.jmx.mbean.session;
import java.io.IOException;
import javax.management.ObjectName;
import quickfix.SessionNotFound;
public interface SessionAdminMBean {
    String getBeginString();
    String getTargetCompID();
    String getTargetSubID();
    ...

对比：

package org.quickfixj.jmx.mbean.connector;
import java.io.IOException;
import javax.management.openmbean.TabularData;
public interface ConnectorAdminMBean {
    String getRole() throws IOException;
    void stop(boolean var1) throws IOException;
    void stop() throws IOException;
    TabularData getSessions() throws IOException;
    String getHostName() throws IOException;
    int getQueueSize();
}

请说明接口ConnectorAdminMbean无法绑定到Class<\T>的原因。谢谢!

已通过将参数类与MBean代理类匹配来解决此问题，即，通过更改：

SessionAdminMBean mBeanConnectorProxy = MBeanServerInvocationHandler.newProxyInstance(jmxConnectionInstance.getmBeanServerConnection(), mBeanConnector, ConnectorAdminMBean.class, true);

至

ConnectorAdminMBean mBeanConnectorProxy = MBeanServerInvocationHandler.newProxyInstance(jmxConnectionInstance.getmBeanServerConnection(), mBeanConnector, ConnectorAdminMBean.class, true);
