Hi,
Did anybody else experience this?
Since update to Jenkins v1.544, we get hit by two errors:
1. Whenever we save some job configuration, the notification-email
adress is emptied and can not be stored again.
2. A subsequent run of that job then crashes at the end (when attempting
to send email) wit the following exception:
ERROR: Processing failed due to a bug in the code. Please report this to
jenkinsci-users@googlegroups.com
java.lang.NullPointerException

If I compare the config.xml of a still untouched job against a broken
job, I can see, that the <recipients>....</recipients> tag has
completely vanished in the broken job:
<!-- Intact job -->
<hudson.maven.reporters.MavenMailer>
<recipients>me@my-mail-address</recipients>
<dontNotifyEveryUnstableBuild>true</dontNotifyEveryUnstableBuild>
<sendToIndividuals>false</sendToIndividuals>
<perModuleEmail>true</perModuleEmail>
</hudson.maven.reporters.MavenMailer>
<!-- Broken job -->
<hudson.maven.reporters.MavenMailer>
<dontNotifyEveryUnstableBuild>true</dontNotifyEveryUnstableBuild>
<sendToIndividuals>false</sendToIndividuals>
<perModuleEmail>true</perModuleEmail>
</hudson.maven.reporters.MavenMailer>
I can fix (sort of) the situation by manually editing the job's
config.xml and then using "Read Configuration from Disk" in the "Manage
Jenkins" menu. Of course whenever the job gets modified via the GUI
again, the job gets broken again.
IMHO, in addition to an actual fix of the bug, the mail function should
be more tolerant regarding invalid input data. (Perhaps logging a
warning like "No recipients - not sending mail").
Cheers
