Jenkins log is polluted with warnings of the form: Ignoring extra contentÂ
The log contains many lines with following content:
jenkins.log.0:Nov 23, 2015 12:00:39 AM org.eclipse.jetty.util.log.JavaUtilLog warn
jenkins.log.0-WARNING: Ignoring extra content
followed by 3 empty lines and then 2 lines containing 3 space
The messag is repeated sometimes after seconds, sometimes after some minutes.
We checked the configuration of the jobs and Jenkins itself, but cannot find any configuration file, which is not well-defined.
Is there any chance to find the cause in order to avoid this message?
