is there any problem with an MBean and other code i write sharing a singleton object?

basically, my mbean listens on a port by connecting to a "Broker" object and acts as a server. i put this into a spearate thread, e.g., my startService() method calls
Thread t = new Thread(this);
t.start();
and my run method loops forever waiting for stuff to do.

I also have a client that shares this same "Broker" object and sends messages to the Broker whenever necessary.

This Broker Object is a Singleton and stays connected
to a remote machine (sort of like a database connection with a pool of 1)

does anyone see a potential problem with this architecture.


thanks,

frank
