      Description

      Hi,

      Our Jenkins server seems to get locked at some point in time.
      Many Jobs are in starvation, waiting for nodes with certain labels/label combinations.
      (i.e. Waiting for next available executor on ...)

      The log shows a lot of these entries:

      Apr 15, 2015 3:44:25 PM SEVERE hudson.triggers.SafeTimerTask run
      
      Timer task hudson.model.Queue$MaintainTask@5d00189f failed

      and also some entries like

      	at jenkins.advancedqueue.sorter.AdvancedQueueSorterQueueListener.onLeft(AdvancedQueueSorterQueueListener.java:47)

      	at hudson.model.OneOffExecutor.run(OneOffExecutor.java:43)
      

      We see theses issues since we updated the Priority Sorter Plugin to version 2.11 (from version 2.9)

      Downgrading to version 2.9 seems to work fine!

          I upgraded Priority-Sorter to 3.0, and Jenkins from 1.611 to 1.612, and this problem re-appeared. Downgrading Priority-Sorter to 2.12 fixed the problem.

          JENKINS-27957 NullPointerException in AdvancedQueueSorter

          Some items do not have names so returning 0 seems to be the only
          option
