    java.lang.NullPointerException
  4. 0

    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: SEVERE: Failed Finalizing set up java.lang.NullPointerException at java.util.StringTokenizer.<init>(Unknown Source) at java.util.StringTokenizer.<init>(Unknown Source) at hudson.model.Items.fromNameList(Items.java:145) at hudson.plugins.parameterizedtrigger.BuildTriggerConfig.getProjectList(BuildTriggerConfig.java:125) at hudson.plugins.parameterizedtrigger.BuildTrigger.buildDependencyGraph(BuildTrigger.java:74) at hudson.util.DescribableList.buildDependencyGraph(DescribableList.java:213) at hudson.model.Project.buildDependencyGraph(Project.java:201) at hudson.model.DependencyGraph.build(DependencyGraph.java:95) at jenkins.model.Jenkins.rebuildDependencyGraph(Jenkins.java:3738) at jenkins.model.Jenkins$20.run(Jenkins.java:2680) at org.jvnet.hudson.reactor.TaskGraphBuilder$TaskImpl.run(TaskGraphBuilder.java:169) at org.jvnet.hudson.reactor.Reactor.runTask(Reactor.java:282) at jenkins.model.Jenkins$7.runTask(Jenkins.java:886) at org.jvnet.hudson.reactor.Reactor$2.run(Reactor.java:210) at org.jvnet.hudson.reactor.Reactor$Node.run(Reactor.java:117) at java.util.concurrent.ThreadPoolExecutor.runWorker(Unknown Source) at java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source) at java.lang.Thread.run(Unknown Source)
