    [Smack-4.1] NullPointerException in roster push


      I'm using Smack 4.1.9, I know it's not maintained any longer, but nevertheless maybe this issue is also present in latest version:


      java.lang.NullPointerException: Attempt to invoke virtual method 'int java.lang.String.indexOf(int)' on a null object reference
             at org.jxmpp.util.XmppStringUtils.parseBareJid(XmppStringUtils.java:124)
             at org.jivesoftware.smack.roster.Roster$RosterPushListener.handleIQRequest(Roster.java:1416)
             at org.jivesoftware.smack.AbstractXMPPConnection$2.run(AbstractXMPPConnection.java:1061)
             at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1113)
             at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:588)
             at java.lang.Thread.run(Thread.java:818)


      It's probably just a simple null pointer based on the fact that the connection is no yet bound maybe (AbstractXMPPConnection.user is null) - in that case the problem is on the server side, which is even more serious.

      Any thoughts?
