Description
We have an email notification which uses a Jelly template. So far it worked ok, but recently we started getting these:
Jan 25, 2012 2:11:23 PM hudson.plugins.emailext.ExtendedEmailPublisher sendMail
WARNING: Could not send email.

Unfortunately I do not have the build log anymore. From what I remember the output was:
Sending email to: $OUR-CONFIGURED-RECIPIENTS
Then nothing and the build would get stuck.
We're not getting the NPE anymore after an upgrade of the Perforce plugin, so you can close this.
The fix for 13317 prevented null values for default subject and body fields which I thought might be related - but it isn't.
The line of code that is causing a NullPointerException is return line in Slave:
public Launcher createLauncher(TaskListener listener)
{ SlaveComputer c = getComputer(); return new RemoteLauncher(listener, c.getChannel(), c.isUnix()).decorateFor(this); }The only thing that could cause a NPE are the dereferences of c, which is the computer. Something has gotten pretty broken in the configuration for Slave.getComputer() to return null. I'd agree I doubt this is the email-ext plugin.
