Jconsole no longer works with Java 6.0, it did with 5.0

Question

Hello,
We are having a very important issue. We have reproduced the situation in 10 out of 10 computers, all with the same result, even in fresh installations.
Using jconsole, we are connecting to the following service (BEA weblogic 10): service:jmx:rmi:///jndi/iiop://host:7001/weblogic.management.mbeanservers.runtime
In the jconsole provided in any revision of Java 5.0 (1.5) it works, that is to say, it is able to connect to the service.
On the other hand, there is no way to accomplish this using Java 6.0. The connection fails with the following error:
Nov 6, 2007 10:27:56 AM com.sun.corba.se.impl.orb.ORBImpl checkShutdownState
WARNING: "IOP01210228: (BAD_OPERATION) This ORB instance has been destroyed, so no operations can be performed on it"

     at sun.tools.jconsole.VMPanel$2.run(VMPanel.java:279)
We have also create our own application to do this and although the same piece of code compiles under both JDKs, it fails to run with exactly the same error under Java 6.0.
Does anyone know why this is happening and if there is a way to work around it?
TIA.

Hi, I faced similar problems access MBeans to Weblogic Server 10 from client under JDK(JRE) 6.0
, but my way of workaround may be helpful:
Do not use jmx support jar files from Weblogic Server10, use that from 9 instead. Here I use
weblogic.jar & webservices.jar
and it works fine.
the following is my test program (looks ugly, but only for test)
public class MyConnection {
    private static MBeanServerConnection connection;
    private static JMXConnector connector;
    public static void initConnection(String hostname, String portString,
            String username, String password) throws IOException,
            MalformedURLException {
        String protocol = "t3";
        Integer portInteger = Integer.valueOf(portString);
        int port = portInteger.intValue();
        String jndiroot = "/jndi/";
        String mserver = "weblogic.management.mbeanservers.domainruntime";
        JMXServiceURL serviceURL = new JMXServiceURL(protocol, hostname, port,
                jndiroot + mserver);
        Hashtable h = new Hashtable();
        h.put(Context.SECURITY_PRINCIPAL, username);
        h.put(Context.SECURITY_CREDENTIALS, password);
        h.put(JMXConnectorFactory.PROTOCOL_PROVIDER_PACKAGES,
            "weblogic.management.remote");
        connector = JMXConnectorFactory.connect(serviceURL, h);
        connection = connector.getMBeanServerConnection();
    public static void getComplidatedObject() throws Exception {
        //String name = "com.bea:Location=examplesServer,Name=examplesServer,ServerRuntime=examplesServer,Type=JDBCServiceRuntime";\
        String name = "com.bea:Name=DomainRuntimeService,Type=weblogic.management.mbeanservers.domainruntime.DomainRuntimeServiceMBean";
        String attribute = "ServerRuntimes";
        ObjectName on = new ObjectName(name);
        Object obj = connection.getAttribute(on, attribute);
        //Method m = obj.getClass().getMethod("getState", new Class[] {});
        //Object result = m.invoke(obj, null);
        //System.out.println(result);
        System.out.println(obj.getClass().isArray());
        System.out.println(obj);
    public static void discovery() throws Exception {
        String mbeanType = "*:*";
        ObjectName patialObjectName = new ObjectName(mbeanType);
        Set mbeans = connection.queryNames(patialObjectName, null);
        long overallTime = System.currentTimeMillis();
        for (Iterator itr = mbeans.iterator(); itr.hasNext();) {
            ObjectName mbean = (ObjectName) itr.next();
            String sMBeanFullName = mbean.getCanonicalName();
            MBeanInfo mbeanInfo = connection.getMBeanInfo(mbean);
            MBeanAttributeInfo mbeanAttrInfoArray[] = mbeanInfo.getAttributes();
            if (mbeanAttrInfoArray == null) {
                continue;
            String sMBeanDescription = mbeanInfo.getDescription();
            String s = mbeanInfo.getClassName();
            System.out.println("====================");
            System.out.println(sMBeanFullName);
            for (int i = 0; i < mbeanAttrInfoArray.length; i++) {
                MBeanAttributeInfo attrInfo = mbeanAttrInfoArray;
if (attrInfo.isReadable()) {
//If attribute datatype is supported, add it to the list for this mbean
String sAttrDataType = attrInfo.getType();
String sAttrName = attrInfo.getName();
String sAttrDescription = attrInfo.getDescription();
System.out.println("Name:" + sAttrName + "\nType:" + sAttrDataType + "\nDesc:" + sAttrDescription);
} //end if
