Connect to JMX MBean from JBoss EAP 6.4 - jmx

Question

I am trying to connect to JMX using my java code from JBoss EAp 6.4, but I am getting an error saying:
java.lang.IllegalArgumentException: MBeanServer argument must be MBean server where this server is registered, or an MBeanServerForwarder leading to that server
My standalone.xml file has:
<subsystem xmlns="urn:jboss:domain:jmx:1.3">
<expose-resolved-model/>
<expose-expression-model/>
<remoting-connector/>
</subsystem>
ports used are:
<socket-binding-group name="standard-sockets" default-interface="public" port-offset="${jboss.socket.binding.port-offset:0}">
<socket-binding name="management-native" interface="management" port="${jboss.management.native.port:7204}"/>
<socket-binding name="management-http" interface="management" port="${jboss.management.http.port:7203}"/>
<socket-binding name="management-https" interface="management" port="${jboss.management.https.port:7205}"/>
<socket-binding name="http" port="7201"/>
<socket-binding name="https" port="7202"/>
<socket-binding name="ajp" port="7206"/>
<socket-binding name="remoting" port="7207"/>
<socket-binding name="txn-recovery-environment" port="7208"/>
<socket-binding name="txn-status-manager" port="7209"/>
<outbound-socket-binding name="mail-smtp">
<remote-destination host="localhost" port="25"/>
</outbound-socket-binding>
</socket-binding-group>
Java Code, I am using is:
_mbeanServer = ManagementFactory.getPlatformMBeanServer();
String domain = "HtmlAdaptor";
HtmlAdaptorServer adapter = new HtmlAdaptorServer();
String domain = "com.mn";
Hashtable<String,String> params = new Hashtable<String, String>();
params.put("name", "JMXHtmlAdaptor");
params.put("port", String.valueOf(_jmxHttpPort));
ObjectName adapterName = new ObjectName(domain, params);
adapter.setPort(_jmxHttpPort);
server.registerMBean(adapter, adapterName);
adapter.setMBeanServer(_mbeanServer);
// _jmxHttpPort = 10099
// ManagementFactory.getPlatformMBeanServer(); returns object of type org.jboss.as.jmx.PluggableMBeanServerImpl
// adapter.getMBeanServer() returns com.sun.jmx.mbeanserver.JmxMBeanServer
// server returns object of type org.jboss.as.jmx.PluggableMBeanServerImpl
I think the adapter getting created is of wrong type.
Any idea how to resolve this issue?
