findBugs doesn't support Java 9 and it seems to be abandonware at this point:
https://github.com/findbugsproject/findbugs/issues/105
https://github.com/gradle/gradle/issues/720
It has been forked, but the fork requires Java 8:
https://github.com/spotbugs/spotbugs
https://github.com/spotbugs/spotbugs/blob/master/docs/migration.rst#findbugs-gradle-plugin
We should migrate once we move to Java 8 if spotbugs is still being actively developed and findBugs continues to be dead.
Additional tasks:
1. Remove the code that disables the Gradle plugin for findBugs (or spotbugs) when building with Java 9.
2. Enable the findBugs plugin in Jenkins for the relevant builds:
https://builds.apache.org/job/kafka-trunk-jdk10/
https://builds.apache.org/job/kafka-pr-jdk10-scala2.12/
