Key: JENKINS-13925
URL: https://issues.jenkins-ci.org/browse/JENKINS-13925
Project: Jenkins
Issue Type: Bug
Components: jabber
Affects Versions: current
Reporter: Ruben Garat
Assignee: kutzi
After upgrading jenkins (1.432 to 1.465), the instant-messenger (to 1.21)
plugin and the jabber (to 1.22) plugin the jabber comunication (using google
talk) stopped working, and started throwing a null pointer exception.

In the 1.22 version of the jabber plugin the line where the nullpointer occurs
is
{code:title=hudson.plugins.jabber.im.transport.JabberIMConnection.java|borderStyle=solid}
for (IMMessageTarget chat : this.groupChats) {
{code}
In the previous version of the jabber plugin I didn´t have any groupChat
defined, so I thought that maybe there was some problem updating that
configuration so I:
* configured a fake group chat
* saved and restarted (this gave an error that it couldn´t use the groupchat
obviously)
* removed the fake group chat
* saved and restarted (now the nullpointer error stopped and everything works
fine)
In the end I think that the fix should be either handling the possibility of a
null groupchat list or detecting that and fixing the configuration before
attempting to connect.
