Hi Thomas,
    Thanks for responding. :) Here is my stack trace.

Here is the code generating it.

Class: SocketConnector.java

....
import alt.java.net.SocketImpl;
.....

    public void aconnect(final SocketHandler socketHandler, final 
ConnectionModel connectionModel) {
        Thread thread = new Thread(new Runnable() {
            public void run() {
                alt.java.net.Socket socket = null;
                try {
                    ConnectionEvent event = new 
ConnectionEvent(connectionModel, ConnectionEvent.CONNECTION_STARTING
);
                    ConnectionEvent vetoEvent = new 
ConnectionEvent(connectionModel, ConnectionEvent.CONNECTION_VETO
ED);
                    fireConnectionStarting(event, vetoEvent);
                    socketHandler.start();
                    if (connectionModel.isSSL()) {
                        socket = new 
SocketImpl(negotiateSSLConnection(connectionModel));
                    } else {
--->>>              socket = new SocketImpl(new 
Socket(connectionModel.getHost(), connectionModel.getPort()));
                    }


It appears the class in question is indeed in the jar I load.

Thank you!!!

Darren
