Hi,

We are running two different web applications in two different instances in jboss-4.0.3 server. If we try to access the jmx-console of one instance running in one port it is opening correctly without and issues.

But we are facing some issues with the other instance jmx-console running on different port.

Please find the issue that we are facing during accessing one of the instance of the jmx-console.
