leventov opened a new issue #7780: Walk over IntelliJ's "constant conditions and expressions" inspection results which are unrelated to null URL: https://github.com/apache/incubator-druid/issues/7780 IntelliJ's "Constant conditions and expressions" inspection mixes nullability-related problems and other types of problems. In Druid, there are 2500+ nullability related problems which makes the analysis impossible. [You can vote for this issue in YouTrack](https://youtrack.jetbrains.com/issue/IDEABKL-4141) to make it more likely that the problem is solved by IntelliJ developers. For now, I [worked that around](https://youtrack.jetbrains.com/issue/IDEABKL-4141#focus=streamItem-27-3506899.0-0) and we can analyze actual bugs, 49 of them below. Please go over the results below and fix the corresponding bugs. ``` <problem>
