I have a maven build job, which since recently started throwing the following error, after the build itself has been completed successfully:

>>>Console output<<<

>>>Console output<<<

In jenkins.log i don't find any issue around the time when the job was executed.

The job itself executes on one of the Slaves.

As far as i can see so far, that error doesn't seem to affect the job in any negative way, but it causes a confusion. Last time when i ran that job and i didn't see that error was 2-3 weeks ago.
Since then i've reconfigured Jenkins to be accessible over HTTPS instead HTTP, but i doubt this has anything to do with the current issue.

I see couple of similar issues (https://issues.jenkins-ci.org/browse/JENKINS-49588 & https://issues.jenkins-ci.org/browse/JENKINS-54547) reported in the past, but they are supposed to be fix in 2.163, moreover i don't find any fingerprint related exceptions. 

Any help would be appreciated. Thanks in advance!
