NullPointerException on second XMPPConnection.connect() attempt

[GoogleCodeExporter]

Hi all,

I get a NullPointerException as I try to reconnect to my xmpp server.
I disconnect during the call to onPause and reconnect in onResume

I can connect and login successfully during the first attempt while I get a
NullPointerException at the second.
Here is an excerpt from my code:

public void login(String username, String password,String resource, String
serviceName) throws RemoteException {

if (c == null || !c.isConnected()) {
    c = new XMPPConnection(serviceName);
    try {
    c.connect();
        ....

And this is what comes from the logcat:
java.lang.NullPointerException
org.jivesoftware.smackx.muc.MultiUserChat$1.connectionCreated(MultiUserChat.java
:114)
at
org.jivesoftware.smack.XMPPConnection.initConnection(XMPPConnection.java:618)
at
org.jivesoftware.smack.XMPPConnection.connectUsingConfiguration(XMPPConnection.j
ava:565)
at org.jivesoftware.smack.XMPPConnection.connect(XMPPConnection.java:991)
at nl.func.fml.service.XMPPServiceImpl$1.login(XMPPServiceImpl.java:73)

The problem occurs with any version of asmack (even with the latest one)

Hi,

I've got an idea/theory whats happening.

You initialize the MultiUserChat after the first connect? That would avaid
MultiUserChat$1.connectionCreated on the first login.

It looks like MultiUserChat depends on ServiceDiscovery, and especially on 
<cinit> of
ServiceDiscovery running before <cinit> of MulitUserChat. That's a horrible 
situation.

I'll see what I can do, but it will require an asmack patch and an upstream bug 
report.

Regards,
  Rene
