NPE for jenkins.queue values

    XMLWordPrintable

Details

    • Bug
    • Status: Open (View Workflow)
    • Minor
    • Resolution: Unresolved
    • core
    • None
    • Jenkins LTS 2.46.3 on Linux, Oracle Java 8.131-1, metrics-plugin 3.1.2.9, prometheus-plugin 1.0.6

    Description

      For currently unkown reasons, we have stuck builds (executors are reported as not available, though they are, we now just cancel the builds)

      If we have these stuck builds, the metrics plugin contains the following values:

      "jenkins.queue.blocked.value" : { "error" : "java.lang.NullPointerException" }, "jenkins.queue.buildable.value" : { "error" : "java.lang.NullPointerException" }, "jenkins.queue.pending.value" : { "error" : "java.lang.NullPointerException" }, "jenkins.queue.size.value" : { "error" : "java.lang.NullPointerException" }, "jenkins.queue.stuck.value" : { "error" : "java.lang.NullPointerException" },
      

      Once I delete the stuck builds, the values report 0 again.
      This first came to our attention because the prometheus-plugin will just crash when this happens.

      In the jenkins.log I see something like on startup (which is repeated a lot of times):

          May be also a bug in the core (null parameters should cause a failure earlier at least), need to check it later

          Is a bug in core, but committing a defence to the metrics plugin
