Can't receive chat message if I don't send one first

Question

I checked out similar questions But I could not solve my problem.

I implemented a chat app using Smack 4.2.

The strange thing is that I can only receive chat messages if I send one one first.

Here is my connection code:

XMPPTCPConnectionConfiguration config = XMPPTCPConnectionConfiguration.builder()  
.setHost(HOST)  
.setPort(PORT)  
.setXmppDomain(serviceName)
.setUsernameAndPassword(USERNAME + "@"+HOST, PASSWORD)  
.setCompressionEnabled(false)  
.setSecurityMode(ConnectionConfiguration.SecurityMode.disabled)
.setSendPresence(true)  
.build();  

connection = new XMPPTCPConnection(config);
connection.connect();
connection.login(); 

And this is how I send the message:

final Message msg = new Message();  
msg.setTo(jid);
msg.setFrom(myjid);
msg.setBody(message.getText().toString());
msg.setStanzaId(rd);
msg.setType(Message.Type.chat);
connection.sendStanza(msg);

How can I receive a message even BEFORE I send one to the other user ?

Thanks!!!

SOLVED

I cannot believe I wasted so much time on this. The problem is that Smack 4.2.0 is buggy (it's a beta version after all). All I needed to do is use Smack 4.1.9 instead.
