    After upgrading to Hudson 1.352/Jabber plugin 1.7/IM plugin 1.6, we are no longer connecting successfully. We were previously fine with Hudson 1.345 and whatever Jabber/IM version was current 4-6 weeks ago. Our Jabber server is ejabberd 2.0.1. There's nothing special about our configuration. A Jabber ID, password, and server. Here are the relevant logs (I hope): {noformat} hudson home directory: C:\dev\hudsonBuilds java.lang.NullPointerException at org.jivesoftware.smack.util.Base64.encodeBytes(Base64.java:636) at org.jivesoftware.smack.sasl.SASLMechanism.challengeReceived(SASLMechanism.java:152) at org.jivesoftware.smack.SASLAuthentication.challengeReceived(SASLAuthentication.java:492) at org.jivesoftware.smack.PacketReader.parsePackets(PacketReader.java:338) at org.jivesoftware.smack.PacketReader.access$000(PacketReader.java:44) at org.jivesoftware.smack.PacketReader$1.run(PacketReader.java:76) java.lang.IllegalStateException: Not connected to server. at org.jivesoftware.smack.XMPPConnection.sendPacket(XMPPConnection.java:729) at org.jivesoftware.smack.NonSASLAuthentication.authenticate(NonSASLAuthentication.java:70) at org.jivesoftware.smack.SASLAuthentication.authenticate(SASLAuthentication.java:335) at org.jivesoftware.smack.XMPPConnection.login(XMPPConnection.java:395) at hudson.plugins.jabber.im.transport.JabberIMConnection.createConnection(JabberIMConnection.java:225) at hudson.plugins.jabber.im.transport.JabberIMConnection.connect(JabberIMConnection.java:121) at hudson.plugins.jabber.im.transport.JabberIMConnectionProvider.createConnection(JabberIMConnectionProvider.java:42) at hudson.plugins.im.IMConnectionProvider.currentConnection(IMConnectionProvider.java:44) at hudson.plugins.jabber.im.transport.JabberIMConnectionProvider.setDesc(JabberIMConnectionProvider.java:25) at hudson.plugins.jabber.im.transport.JabberPublisherDescriptor.<init>(JabberPublisherDescriptor.java:114) at hudson.plugins.jabber.im.transport.JabberPublisher.<clinit>(JabberPublisher.java:87) at sun.reflect.GeneratedSerializationConstructorAccessor52.newInstance(Unknown Source) at java.lang.reflect.Constructor.newInstance(Constructor.java:513) at com.thoughtworks.xstream.converters.reflection.Sun14ReflectionProvider.newInstance(Sun14ReflectionProvider.java:76) at hudson.util.RobustReflectionConverter.instantiateNewInstance(RobustReflectionConverter.java:327) at hudson.util.RobustReflectionConverter.unmarshal(RobustReflectionConverter.java:176) at com.thoughtworks.xstream.core.TreeUnmarshaller.convert(TreeUnmarshaller.java:82) at com.thoughtworks.xstream.core.AbstractReferenceUnmarshaller.convert(AbstractReferenceUnmarshaller.java:63) at com.thoughtworks.xstream.core.TreeUnmarshaller.convertAnother(TreeUnmarshaller.java:76) at com.thoughtworks.xstream.core.TreeUnmarshaller.convertAnother(TreeUnmarshaller.java:60) at com.thoughtworks.xstream.converters.collections.AbstractCollectionConverter.readItem(AbstractCollectionConverter.java:71) at hudson.util.CopyOnWriteList$ConverterImpl.unmarshal(CopyOnWriteList.java:186) at hudson.util.DescribableList$ConverterImpl.unmarshal(DescribableList.java:229) at com.thoughtworks.xstream.core.TreeUnmarshaller.convert(TreeUnmarshaller.java:82) at com.thoughtworks.xstream.core.AbstractReferenceUnmarshaller.convert(AbstractReferenceUnmarshaller.java:63) at com.thoughtworks.xstream.core.TreeUnmarshaller.convertAnother(TreeUnmarshaller.java:76) at com.thoughtworks.xstream.core.TreeUnmarshaller.convertAnother(TreeUnmarshaller.java:60) at hudson.util.RobustReflectionConverter.unmarshallField(RobustReflectionConverter.java:286) at hudson.util.RobustReflectionConverter.doUnmarshal(RobustReflectionConverter.java:229) at hudson.util.RobustReflectionConverter.unmarshal(RobustReflectionConverter.java:177) at com.thoughtworks.xstream.core.TreeUnmarshaller.convert(TreeUnmarshaller.java:82) at com.thoughtworks.xstream.core.AbstractReferenceUnmarshaller.convert(AbstractReferenceUnmarshaller.java:63) at com.thoughtworks.xstream.core.TreeUnmarshaller.convertAnother(TreeUnmarshaller.java:76) at com.thoughtworks.xstream.core.TreeUnmarshaller.convertAnother(TreeUnmarshaller.java:60) at com.thoughtworks.xstream.core.TreeUnmarshaller.start(TreeUnmarshaller.java:137) at com.thoughtworks.xstream.core.AbstractTreeMarshallingStrategy.unmarshal(AbstractTreeMarshallingStrategy.java:33) at com.thoughtworks.xstream.XStream.unmarshal(XStream.java:926) at hudson.util.XStream2.unmarshal(XStream2.java:76) at com.thoughtworks.xstream.XStream.unmarshal(XStream.java:912) at com.thoughtworks.xstream.XStream.fromXML(XStream.java:856) at hudson.XmlFile.read(XmlFile.java:126) at hudson.model.Items.load(Items.java:106) at hudson.model.Hudson$12.run(Hudson.java:2097) at org.jvnet.hudson.reactor.TaskGraphBuilder$TaskImpl.run(TaskGraphBuilder.java:146) at org.jvnet.hudson.reactor.Reactor.runTask(Reactor.java:259) at hudson.model.Hudson$3.runTask(Hudson.java:647) at org.jvnet.hudson.reactor.Reactor$2.run(Reactor.java:187) at org.jvnet.hudson.reactor.Reactor$Node.run(Reactor.java:94) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:886) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:908) at java.lang.Thread.run(Thread.java:619) {noformat}
