The following code produces a FP from Java rule S1170. private static long nextID = 1L; private final long localID = nextID++; // FP The rule suggests to make this final field static, too. But obviously it cannot be static.

Thanks for the detailed report, I was able to reproduce the issue. This is a quite old rule and in indeed doesn’t check if the field is used in non-static members. I created a ticket to fix it: https://sonarsource.atlassian.net/browse/SONARJAVA-4749 Best, Margarita
