Findbugs issues not reported correctly on Jenkins master jobs?

I've pushed this patch to master: https://gerrit.ovirt.org/#/c/75994/ Jenkins showed no findbugs error and I moved on to merging it Then I've pushed the same patch to 4.1: https://gerrit.ovirt.org/#/c/76803/ And it resulted in two findbugs errors (though minor and style related): http://jenkins.ovirt.org/job/ovirt-engine_4.1_find-bugs_created/898/findb... Running findbugs manually in my environment on master did report these two issues so I'd expect the master jobs to report them as well.
