The Solaris native threads VM (up to and including JDK1.2beta3) hangs if an RMI server has called System.runFinalizersOnExit(true) and then calls System.exit(), try the following:

-- Foo.java -------------------------------------

import java.rmi.*;

public interface Foo extends Remote {
}

-- FooImpl.java ---------------------------------

import java.rmi.*;
import java.rmi.server.*;

public class FooImpl extends UnicastRemoteObject implements Foo {

    public FooImpl() throws RemoteException {}

    public static void main(String[] args) {
        try {
            System.runFinalizersOnExit(true);
            FooImpl foo = new FooImpl();

            System.out.println("Exiting...");
            System.exit(0);
        }
        catch (Exception e) {
            e.printStackTrace();
        }
    }
}

Actually the (native threads) VM hangs whenever you try and close a socket that is doing an accept() but BugId 4055180 suggests that this is an application bug and not a VM bug.
