I know you probably don't want to hear "its works in my environment", but it does. And it works on the CI machines[1]. And it works on many other developers machines. I am sorry you are having trouble with the build, but I can assure you it is not the build.

BTW, that CI job is building head. And aside from some recent issues due to a CI env migration all the jobs have been passing for quite some time. Certainly HEAD is "moving" in terms of it is actively developed. But it is not moving in terms of builds failing or what-have-you.

As far as FindBugs and CheckStyle, again I direct you to the CI jobs. Currently we only enforce CheckStyle. And you can see that the jobs are passing CheckStyle (no red). Although tbh alot of the FindBugs stuff you are just misreading. Like that last snippet actually just lists every thing that FindBugs checked. FindBugs is verbose, not sure what to tell you. They have a website where you can complain
