OS: Linux Debian
Jenkins: v1.536
email-ext: v2.35.1
After updating to the latest jenkins version (v1.536) i get this error when saving a project which has the email-ext plugin enabled
EDIT:
It looks like it has to do with missing options in the config (the config hasn't changed for weeks now..) but with a litle bit of guessing i found what options were required. So maybe a fix for this issue could be to have required fields and give the user feedback on what fields he has to fill instead of this raw error

[JENKINS-20198] Failed to instantiate class hudson.plugins.emailext.ExtendedEmailPublisher

added a comment - I found that the problem is with the mail trigger, so i add a mail trigger and save (that works correctly) but when i open my config after that it show an empty line for the build trigger and it throws the error above when saving

After save: http://i.imgur.com/ciHCJBb.png We have the same problem. Sometimes save works and sometimes we got the above described error. I found out that config.xml has <null> in <configuredTriggers> and therefor is not able to run the job. If I put in the correct values manually and reload jenkins settings. Everything works fine. So I think its a problem of the job save mechanism.

Ubuntu 12.04 LTS

Environment:
Ubuntu 12.04 LTS
Jenkins 1.5.36
Email-ext 2.35.1 I linked this issue to one that looks similar that was related to some new Stapler stuff in core, it is supposedly fixed in 1.536, but there may still be some issues.
Got this after upgrading Jenkins from v1.535 to v1.536 (and EmailExt plugin from v2.34 to v2.35.1). Looks like the same thing as JIRA-20030. Job configuration files end up with <null/> tags, in place of the prior content of the <configuredTriggers> tag. Causes NPEs, when you try to run the job.
| OS: | Windows 2008x64 |
|---|---|
| Jenkins: | v1.536 |
| EmailExt: | v2.35.1 |
No, I don't think this is the same thing as JENKINS-20030 at all. That was a change in the way that parameters were parsed from the job config page, this is completely different. I believe it has to do with changes that were made in 1.536.
On 1.536 whether I downgrade to 1.535 and/or Email Ext 2.34 I get a failure on saving every time. May I suggest you submit this only to the LTS plugin repository rather than the main one if you don't test it on the main stable releases? It feels like almost every Jenkins update I do breaks something new in this plugin 
The failure seems to be the <null/> trigger that created. I have to remove that to fix the error (just in case anyone else runs into the same problem). It seems to be working on on 1.535 now.
Yes, 1.536 adds the <null/> trigger element because of some breaking change in the way JSON is done, so reverting back to 1.535 with the changes that 1.536 made would still cause you problems.
There is no way to release "only to the LTS plugin repository" the Jenkins release process doesn't work that way. If you want a more stable environment, use the LTS, that is what it is for. The plugin is developed against the LTS for a reason.
I believe the <null/> tags were inserted when the plugin failed to upgrade the <configuredTriggers> content, for the new plugin version. Having previously experience with problems like this, I always install the job configuration history plugin. Using that information, I reverted the job configuration XML files to a prior-to-upgrade copy. This fixed the problem.
I'll have to closely review any saved job configuration changes, until the issue is fixed.

The problem is with the empty trigger line (null value as said above in the comments)

added a comment - I got the same failure. Same here. The configuration for the job is not saved and any email triggers are saved with a <null/> tag.
removed override of newInstance for EmailTriggerDescriptor that is not really needed, this works around the new behavior added in Jenkins 1.536
I installed the hpi onto Jenkins 1.536 under RHEL 6; added "Editable Email Notification" as a Post-Buid step to a job; configured the job and saved the configuration.
I did a "Build Now" and the build succeeded and email was successfully sent.
Code changed in jenkins

Log:
Fix JENKINS-20198
Removed override of newInstance for EmailTriggerDescriptor. It's not needed because the email triggers should have DataBoundConstructor annotations. The new BindingInterceptor in hudson.model.Descriptor caused an issue with the newInstance method.
Hello,
This trouble is probably still there in the last LTS Jenkins version - Jenkins ver. 1.554.2
Could you please to fix it there? It is quite urgent now - saving any changes in configuration causes an exception.
Thank you.

Be aware that the plugin is only tested with the most recent LTS release, any releases after that have not received any testing and so there are possibly breaking issues in the core. Please post the config.xml that is "missing options".
