[java:S1170] FP when field is initialized by static input

Sorry, my example was indeed not sufficient. You don’t need the complete class though. And no, I’m not suggesting to evaluate the name.

public class C
{
    private static long nextID = 1L;
    private final long localID = nextID++; // FP
    
    public int getID()
    {
        return localID;
    }
}

So, the rule would just need to look at the whole class, and if the field is used in a non static context.
