JConsole unable to connect to PID

Question

Hi All,
First off, I know very little about JDKs, let alone JConsole.  We're using the tool to monitor a process in our test environment, however the same commands do no work in our production environment.  These are the commands I'm using, and the error which I'm receiving -
$ cd /usr/java6_64/bin
$ jconsole &
[1]     19202262
I am presented with:
JConsole: New Connection
* Local Process
run.jar.start  (This is the Name I select) along with the associated PID.
Click Connect
This is the error:
"Connection Lost; Reconnect?
The connection to "PID#" has been lost because the remote process has been terminated.
Would you like to reconnect?"
I am not experiencing this issue in our test environment. I do not know where to start to begin trouble shooting the issue.
What other information would you like?
Thanks,
Steve

I will answer my own question.
Yes you can use MX4J with JConsole. The problem I was having was because of the way we block our main thread.
When we start our services we kick off a new thread from the main thread and then our main thread goes into a wait where it listens for IO from the user using the System.in.
BufferedReader r = new BufferedReader(new InputStreamReader(System.in));
String in = null;
do {
// Waits for user input from the console
in = r.readLine(); //blocks the main thread, this blocks the JConsole from being attaching to the MBeanServer
