Creating an empty logger crashs Jenkins

    XMLWordPrintable

Details

    Description

      With support bundle plugin installed, when I create a new logger and let the logger classname field empty, Jenkins crashes when I click Save button.

      On save, Jenkins starts to write tons of exception logs and is not responsible anymore. Killing the JVM is the only way to stop it doing this.

      Logged exception looks like this one:

      Exception in thread "RequestHandlerThread[#10]" java.lang.ClassCircularityError: hudson/logging/LogRecorder
	at com.cloudbees.jenkins.support.impl.JenkinsLogs$CustomHandler.publish(JenkinsLogs.java:507)

      On 1.580, faulty configuration is saved on disk. To restart the instance, faulty configuration file $JENKINS_HOME/log/<faulty>.xml must be removed.

      On 1.606, configuration is not saved, so restarting the instance works.
