Issue Type: Bug Bug
Assignee: huybrechts
Components: parameterized-trigger-plugin
Created: 27/Jan/15 7:16 PM
Description:

hudson.tasks.BuildTrigger#getChildProjects(hudson.model.ItemGroup) doesn't check if childProjects is null.

Even though childProjects is checked for null in the constructor, this can happen if a BuildTrigger is deserialized from an invalid configuration.

What's worse, is that due to JENKINS-26643, this can prevent Jenkins from starting. Example:
