[JIRA] [core] (JENKINS-16845) NullPointer in getPreviousBuild

Thu, 16 May 2013 01:18:02 -0700

gitt commented on Bug JENKINS-16845

I get similar error with 1.509.1:

  • I had several jobs created in Jenkins 1.501. The problem was that "Test Result Trend" chart was often not shown and in log file there were NullPointer/getPreviousBuild() exceptions.
  • Then I upgraded to 1.509.1, deleted all old builds and "Test Result Trend" charts were shown again. But only for some time. After several new builds they disappeared and this is what i see in Jenkins log again:
