At the JUG meetup in Lausanne on Nov 14, I was said that SpotBugs does not actually solve this issue in the latest release. They fixed some other issues, but not that one.
Probably to be looked at again when the switch to SpotBugs lands into the plugin-pom https://github.com/jenkinsci/plugin-pom/pull/128
Yes, https://github.com/spotbugs/spotbugs/issues/711 is reported to be fixed in 3.1.7
