RMI server doesn't reliably start

Question

I have a simple RMI server with one object that has one method:
public interface Foo extends Remote {
      // the Blah class is Serializable
      java.util.ArrayList <Blah> getListOfBlahs (String name);
public class FooImpl impelments Foo {
    java.util.ArrayLIst <Blah> getListOfBlahs (String name) {
             // Do whatever...
}My server is pretty simple at the moment and looks like this:
    public static void main (String [] args) {
        try {
            Foo stub = (Foo)UnicastRemoteObject.exportObject (new FooImpl(), 0);
            Registry registry = LocateRegistry.getRegistry();
            try {
                registry.unbind ("foo");
            } catch (NotBoundException ex) {
                System.out.println ("the thing isn't bound at the moment");
            registry.bind ("foo", stub);
            System.out.println ("Server Ready.....");
        } catch (RemoteException rmi) {
            rmi.printStackTrace ();
        } catch (AlreadyBoundException ex) {
            ex.printStackTrace ();
    }The problem is that sometimes when I start it, it promptly dies again with no error messages.
A couple things:
1) The server runs on a Fedora Core 8 machine, and the firewall is shutdown.
2) Before I run the server, I make sure to start the rmiregistry.
Usually I have to start the server a few times before the process doesn't just die again.
My hypothesis is that it's trying (unsuccessfully) to bind my Foo class to a port that is in use, but why don't I get an error?
Are there other log files to look at? Maybe in /var/log somewhere?
Thanks

Answer 1

Yep.
After making some static references to the remote objects, the server starts and stays running:
class Server {
   private static FooImpl foo;
    public static void main (String [] args) {
        try {
            foo = new FooImpl ();
            Foo stub = (Foo)UnicastRemoteObject.exportObject (foo, 0);
            Registry registry = LocateRegistry.getRegistry();
            try {
                registry.unbind ("foo");
            } catch (NotBoundException ex) {
                System.out.println ("the thing isn't bound at the moment");
            registry.bind ("foo", stub);
            System.out.println ("Server Ready.....");
        } catch (RemoteException rmi) {
            rmi.printStackTrace ();
        } catch (AlreadyBoundException ex) {
            ex.printStackTrace ();
