Deselecting the "Build when a change is pushed to GitHub" checkbox for an existing project, causes a full page NullPointerException stack trace to appear and results in every job that uses GitHub webhooks on the same instance of Jenkins to fail.

This change also causes the full page stack trace to be thrown every time the job's configuration is saved, only reverting the change with the Job Configuration History plugin allows Jenkins to be put back to normal.

Additionally, it appears this causes a number of other core Jenkins tasks to fail with NullPointerExceptions. I hope to provide a ZIP from the Support plugin tomorrow that'll provide additional details.

Here's what's removed from the job config.xml that causes the failure:

<triggers>
  <com.cloudbees.jenkins.GitHubPushTrigger plugin="github@1.22.4">
    <null/>
    <spec></spec>
  </com.cloudbees.jenkins.GitHubPushTrigger>
</triggers>

Here's the stack trace that happens when trying to save any edit to that job.

Environment

Original: Jenkins 2.30
Debian 8.6, 64-bit, 3.16.36-1+deb8u2
Jenkins is run directly, not through docker or tomcat.
nginx is used as revert proxy, but webhooks are exposed directly to Jenkins
Jenkins was installed from the pkg.jenkins-ci.org apt repo

Description

Original: Deselecting the "Build when a change is pushed to GitHub" checkbox for an existing project, causes a full page NullPointerException stack trace to appear and results in every job that uses GitHub webhooks on the same instance of Jenkins to fail.

This change also causes the full page stack trace to be thrown every time the job's configuration is saved, only reverting the change with the Job Configuration History plugin allows Jenkins to be put back to normal.

Additionally, it appears this causes a number of other core Jenkins tasks to fail with NullPointerExceptions. I hope to provide a ZIP from the Support plugin tomorrow that'll provide additional details.

Here's the stack trace that happens when trying to save any edit to that job.

New: Deselecting the "Build when a change is pushed to GitHub" checkbox for an existing project, causes a full page NullPointerException stack trace to appear and results in every job that uses GitHub webhooks on the same instance of Jenkins to fail.

This change also causes the full page stack trace to be thrown every time the job's configuration is saved, only reverting the change with the Job Configuration History plugin allows Jenkins to be put back to normal.

Additionally, it appears this causes a number of other core Jenkins tasks to fail with NullPointerExceptions. I hope to provide a ZIP from the Support plugin tomorrow that'll provide additional details.

Here's what's removed from the job config.xml that causes the failure:
{code}
<com.cloudbees.jenkins.GitHubPushTrigger plugin="github@1.22.4">
<null/>
<spec></spec>
</com.cloudbees.jenkins.GitHubPushTrigger>
{code}

Here's the stack trace that happens when trying to save any edit to that job.

Description

Original: Deselecting the "Build when a change is pushed to GitHub" checkbox for an existing project, causes a full page NullPointerException stack trace to appear and results in every job that uses GitHub webhooks on the same instance of Jenkins to fail.

This change also causes the full page stack trace to be thrown every time the job's configuration is saved, only reverting the change with the Job Configuration History plugin allows Jenkins to be put back to normal.

Additionally, it appears this causes a number of other core Jenkins tasks to fail with NullPointerExceptions. I hope to provide a ZIP from the Support plugin tomorrow that'll provide additional details.

Here's what's removed from the job config.xml that causes the failure:
{code}
<com.cloudbees.jenkins.GitHubPushTrigger plugin="github@1.22.4">
<null/>
<spec></spec>
</com.cloudbees.jenkins.GitHubPushTrigger>
{code}

Here's the stack trace that happens when trying to save any edit to that job.

New: Deselecting the "Build when a change is pushed to GitHub" checkbox for an existing project, causes a full page NullPointerException stack trace to appear and results in every job that uses GitHub webhooks on the same instance of Jenkins to fail.

This change also causes the full page stack trace to be thrown every time the job's configuration is saved, only reverting the change with the Job Configuration History plugin allows Jenkins to be put back to normal.

Additionally, it appears this causes a number of other core Jenkins tasks to fail with NullPointerExceptions. I hope to provide a ZIP from the Support plugin tomorrow that'll provide additional details.

Here's what's removed from the job config.xml that causes the failure:
{code}
<triggers>
  <com.cloudbees.jenkins.GitHubPushTrigger plugin="github@1.22.4">
    <null/>
    <spec></spec>
  </com.cloudbees.jenkins.GitHubPushTrigger>
</triggers>
{code}

Here's the stack trace that happens when trying to save any edit to that job.
