We have seen the same logs. Our log looks like:

2008-08-05 01:30:39,900  WARN [AutoCloseEventGenerator0](MSNValidator.java:53)- unsupported protocol : MSNP12 MSNP11 MSNP10 MSNP9 MSNP8 unsupported protocol : MSNP12 MSNP11 MSNP10 MSNP9 MSNP8
    at net.sf.jml.protocol.incoming.IncomingVER.messageReceived(IncomingVER.java:58)
    at net.sf.jml.protocol.MsnSession$1.messageReceived(MsnSession.java:105)

We also got a NullPointer when check if verified in IncomingUSR.

From IncominUSR.java:

    public boolean isVerified() {
        if (isLoginIntoSB())
            return true;
        if (protocol.before(MsnProtocol.MSNP10)) { // THIS LINE GENERATES NULLPOINTER BELOW
            return "1".equals(getParam(3));
        }
        return "1".equals(getParam(2));
    }

2008-08-05 01:31:11,172  WARN [AutoCloseEventGenerator0](MsnHandler.java:348)- Got unhandled exception: null java.lang.NullPointerException

    at net.sf.jml.protocol.MsnSession$1.messageReceived(MsnSession.java:105)

It seems like MS has made some changes to the protocol. I have tried some other 3:d party messengers and they also have probs to logging in.

Hi,

try updating the sources. There is a commit which solved the things.

[Daniel Henninger]

And due to the nature of these changes, I'm going to put out another "official release" today with the fix from trunk (amongst other things).

[Mattias Jonsson]

I have made some quick fixes to get it up and running temporarly => If not supported set MSN protocol to highest supported version. In this case MSNP12.

MsnMessage.java

    protected MsnMessage(MsnProtocol protocol) {
        //Fix start
        if(protocol == null) {
            protocol = MsnProtocol.MSNP12;
        }
        //Fix stop
        this.protocol = protocol;
    }

IncomingVER.java

    protected void messageReceived(MsnSession session) {
        super.messageReceived(session);
        MsnProtocol[] supportedProtocol = getSupportedProtocol();
        //Fix start
        if(supportedProtocol.length == 0) {
            supportedProtocol = new MsnProtocol[1];
            supportedProtocol[0] = MsnProtocol.MSNP12;
        }
        //Fix stop
        if (supportedProtocol.length > 0) {
            session.getMessenger().setSupportedProtocol(supportedProtocol);
            ((BasicMessenger) session.getMessenger())
                    .setActualMsnProtocol(supportedProtocol[0]);
        } else {
            throw new UnsupportedProtocolException(
                    ((OutgoingVER) getOutgoingMessage()).getSupportedProtocol());
        }
    }

It seems to work for now but is not a pleasant way to handle the problem.

I grabbed the new build ... thanks for the quick fix.
