Races in 4.0rc1

Hi

 

Trying out XMPP for the first time, with 4.0rc1, operating against an ejabberd 2.10 host.

 

I've come up against problems with connecting. Firstly :

 

       XMPPConnection connection = new XMPPTCPConnection(config);

 

        connection.connect();

 

        connection.login("user", "password1");

 

Was bombing on the connection due to "No non-anonymous SASL connection modes" type error.

 

This is because the all-important message[1] containing the supported SASL modes has not arrived by the time login() is executed. I can't tell if that's because the server is slow, or that the pause is in sending the outbound queued message. Either way, it's a race condition, and inserting

 

Thread.sleep(30000);

 

between connect and login fixes it, ugly though that may be.

 

Secondly, I seemed to have to disable TLS with

config.setSecurityMode(ConnectionConfiguration.SecurityMode.disabled);

 

If I don't, then by the time we get to SASLMechanism:170 "sc.hasInitialResponse()", the answer is 'no', and we end up sending 'null' as authenticationText (Which unsurprisingly doesn't work).

 

tls start and proceed messages have been exchanged [2], so I don't know why it's the case that it's not happy in that route.
